THE RULEBOOK

Understand it. Then remember it.

A complete reference for the course, with examples and a solving routine for every topic.

;Connect complete sentences

Find the basic sentence

An independent clause is a complete sentence: it tells us who or what the sentence is about and gives that subject a main verb. Try reading the basic sentence by itself. Extra descriptions can make it longer without changing its basic structure.

The scientist, known for her work on birds, published the results. → The scientist published the results.

“The scientist published the results” stands alone. The words between the commas add information about the scientist.

Check what the opening words do

Words such as “although,” “because,” and “when” can make an otherwise complete sentence depend on another thought. An -ing word can describe an action without being the sentence’s main verb. Look for the full verb: “is studying” works as a main verb; “studying” alone often does not.

Although the scientist studied the birds, she still had questions. / The scientist studying the birds had questions.

In the first example, “although” makes us wait for the main point: “she still had questions.” In the second, “studying the birds” describes the scientist; “had” is the main verb.

Two complete sentences need a proper join

When two complete sentences sit next to each other, a period or semicolon can separate them. A comma by itself cannot do that job.

The trial ended; the team checked the results.

The first statement says what the trial did: “The trial ended.” The second says what the team did: “The team checked the results.” Each has its own subject and main action and leaves no unfinished opening or missing information. The semicolon separates those two complete statements.

A comma can work with a joining word

A comma followed by and, but, or another FANBOYS word can connect two complete sentences. FANBOYS stands for for, and, nor, but, or, yet, so.

The trial ended, but the team needed more data.

Both sides are complete sentences. Comma + but connects them and shows the contrast.

One person can do two connected things

Two actions can share one subject when a word such as and joins them. In an ordinary short pair, do not separate the actions with a comma or semicolon.

The team collected samples and checked the results.

The team does both things: collected and checked. “Checked the results” has no separate subject here, so this is not a pair of independent clauses.

An opening thought may need a comma

When an opening thought starts with a word like although or because, attach it to the main sentence. Do not end the opening thought with a period or semicolon.

Because the trial ended early, the team had time to check the results.

“The trial ended early” tells us what happened, but adding “because” turns it into a reason waiting for a main point. That point is “the team had time to check the results.” The comma attaches the opening reason to it. If the because part follows the main point and supplies its needed reason, it usually needs no comma.

However does not do the job of but

Words such as however and therefore show a connection in meaning. They cannot, by themselves, join two complete sentences with just a comma.

The trial ended; however, the team kept working.

A semicolon closes the first complete sentence. However begins the next one and is followed by a comma. A period before However would also make a correct structure.

Check which sentence a transition belongs to

However or therefore can appear inside a sentence or at its end. First decide what the word means there. Then put the sentence break in the right place.

We expected a long trial. The trial was brief, however; the analysis took weeks.

However contrasts the brief trial with the long trial we expected. It belongs with “The trial was brief,” so the semicolon goes after it. The next complete sentence begins “the analysis.”

A long passage is not automatically two complete sentences. A short one can be. Check the structure, not the length.

,Set off extra information

Try taking the extra part out

Extra information adds a description that is not needed to identify which person or thing is meant. Set it aside and check that the main sentence still works and still names the intended person or thing.

Ada Lovelace, an early computing pioneer, wrote about the machine.

“Ada Lovelace wrote about the machine” already identifies Ada and gives the main point. The added description takes commas.

Use a matching pair in the middle

Extra information in the middle needs a clear beginning and end: two commas, two dashes, or matching parentheses. At the end, extra information introduced by a comma or dash needs no second comma or dash. Parentheses still need a closing “)”.

The machine—an early design—used punched cards.

The dashes surround “an early design.” Removing the whole insertion, including both dashes, leaves “The machine used punched cards.” A comma cannot replace just one of the two dashes.

Some descriptions identify which one

If the description is needed to identify which person or thing is meant, keep it attached without a pair of commas. Being able to delete words is only a first check; check the meaning too.

The students who finished early checked their work.

“Who finished early” tells us which students. Commas would make that information extra and change what the sentence says.

Read across a long interruption

When an answer choice closes extra information, look back for its opening punctuation. The main sentence may resume several lines after it began.

The machine, designed years before computers became common, never reached production.

The comma after common closes the description that began after machine. The main sentence is “The machine never reached production.”

Do not put commas around every description. Some descriptions tell the reader which person or thing you mean.

,Know when to use no punctuation

Keep the subject with its main verb

Do not put a single comma, colon, or semicolon between who or what the sentence is about and its main verb. A long subject does not change this.

The collection of maps from several different centuries remains on display.

The collection remains on display. No punctuation belongs between centuries and remains.

Keep the verb with the words it needs

A verb may need the next words to finish its meaning. Do not add punctuation just because you pause when reading aloud.

The researchers discovered three new species.

Discovered needs to tell us what was discovered. No comma or colon belongs between discovered and three.

Keep a needed name attached

A title or description may need a name to identify the person. Keep them together in that case. A name added to an already identified person can be extra information instead.

Author Toni Morrison wrote Beloved. / Our only guest speaker, Toni Morrison, answered questions.

“Author Toni Morrison” names the author as one connected phrase. In the second example, “our only guest speaker” already identifies one person, so the name can be added between commas. Removing the whole name and its commas leaves “Our only guest speaker answered questions.” Do not decide from the presence of a title or name alone.

Do not split a needed detail

Keep words such as that and which attached when they introduce information the sentence needs. Check the whole meaning before adding commas.

The team confirmed that the sample was safe.

“That the sample was safe” tells us what the team confirmed. A comma after confirmed would split words that belong together.

Punctuation follows sentence structure, not where you happen to take a breath.

,Introduce an explanation or list

Finish the setup first

A colon can introduce a list, example, or explanation. The words before it must already work as a complete sentence.

The team needed three items: gloves, jars, and labels.

“The team needed three items” can stand alone. The list explains which three items.

The part after the colon can be short

The words after a colon do not have to form another complete sentence. They just need to explain or name what the setup introduces.

The test had one goal: accuracy.

Accuracy names the goal. The setup before the colon is complete even though accuracy is only one word.

Do not interrupt an unfinished setup

Do not put a colon directly after words that are still waiting for the rest of their meaning, such as a verb introducing a needed list.

The kit includes gloves, jars, and labels.

“The kit includes” is unfinished here: includes what? Keep the list attached. A single dash can also introduce an explanation after a complete setup when the answer choices call for it.

The presence of a list does not automatically mean you need a colon.

,Punctuate lists

Find the items first

Use commas to separate three or more ordinary list items. First decide where each item begins and ends. Do not put a comma inside a single item just because it contains several words.

We visited the old observatory, the science museum, and the new library.

There are three places. Each place stays together; the commas separate the places.

Use semicolons for a list with commas inside it

When list items already contain commas, semicolons can make the larger divisions clear. In this kind of list, the items do not each need to be complete sentences.

The trip included Lima, Peru; Quito, Ecuador; and Bogotá, Colombia.

Each city and country belong together. The semicolons separate the three destinations.

Some describing words can take a comma

Two describing words may need a comma when they describe the same thing separately. Try putting and between them or reversing their order. If the words build one description together, keep them together.

A quiet, spacious room. / Three large glass jars.

Quiet and spacious both describe the room separately. In “three large glass jars,” “glass jars” names the kind of object, “large” gives its size, and “three” counts the jars. These words build one phrase rather than separate list items.

Two connected items usually need no comma

In a simple pair joined by and or or, keep the pair together. Check whether a nearby comma is doing another job, such as closing extra information.

The team collected and labeled the samples.

Collected and labeled are two connected actions. There is no extra information to close, so no comma belongs between them.

A comma inside a city-and-country pair is not the boundary between two whole destinations.

’sApostrophes: one, many, or ownership?

More than one usually needs just s

An apostrophe does not make a word plural. To say more than one, use the ordinary plural spelling.

The scientists compared three samples.

Scientists and samples mean more than one. Neither word shows ownership, so neither needs an apostrophe.

One owner usually takes apostrophe + s

When something belongs to one person or thing, usually add apostrophe + s.

The scientist’s notes were clear.

The notes belong to one scientist. Put the apostrophe before the s.

For plural owners ending in s, put the apostrophe after it

First spell the plural owner. If that plural already ends in s, put the apostrophe after the s. If it does not, add apostrophe + s.

The scientists’ notes. / The children’s drawings.

Scientists already ends in s. Children is already plural without s, so children’s needs apostrophe + s.

Its means belonging to it

Its shows ownership. It’s means it is or it has. Other ownership words such as their, whose, and yours do not need an apostrophe.

The museum changed its hours. / It’s been closed for repairs.

The hours belong to the museum, so use its. In the second sentence, it’s means it has.

Count the owners, not the things they own. One scientist can have many notes.

v.Match the subject and verb

Find who or what goes with the verb

A verb must match its subject. For common present-tense action verbs, use the s form with he/she/it and the form without s with I/you/we/they. Check familiar pairs such as “it is” and “they are,” or “she has” and “they have.”

The sensor works. / The sensors work.

One sensor works like it works. Several sensors work like they work. Do not use the noun-plural s rule for verbs.

Look past the words in between

Words between the subject and verb can distract you. Find the main word that names who or what the verb describes.

The quality of the measurements is important.

Quality is the subject, not measurements. Read the shorter version: “The quality is important.”

One of many is still one

In a sentence such as one of the samples is missing, one controls the verb. Each and every also point to one item at a time.

Each of the samples contains water.

Each means each single sample, so contains fits. The nearby plural samples does not control this verb.

The subject may come after the verb

If the sentence starts with words such as there or among, ask what is actually there. You can mentally put the sentence in a more familiar order.

On the shelf are two jars.

What is on the shelf? Two jars. Read “Two jars are on the shelf,” so are fits.

Check joining words and groups

Two different subjects joined by and usually take a plural verb. With or or nor, the nearer subject guides the choice. A group spoken of as one unit takes a singular verb.

The teacher and the students are ready. / Either the jars or the box is missing. / The team is ready.

And joins more than one person. In the second sentence, box is nearest the verb. In the third, the team is treated as one unit.

The nearest noun is not necessarily the subject. Find what the sentence actually says is doing or being something.

v.Find the main verb

Does the sentence still need its main verb?

Find the subject connected to the blank and check whether that subject already has its main verb. A verb inside a description may belong to a different part of the sentence. An -ing form or to + verb cannot usually finish the main statement on its own, though helping words can make a full verb such as “is testing.”

The scientist testing the samples discovered a pattern.

Testing describes the scientist. Discovered gives the main action. Without discovered or another complete main verb, the statement would be unfinished.

An -ing form can attach another action

Once the sentence has a main verb, an -ing form can add a description or result. A second unconnected main verb would create a problem.

The scientist changed the method, improving the results.

“The scientist changed the method” gives the main subject and action. “Improving the results” adds what the change accomplished. To make a second main action, a connection is needed: “The scientist changed the method and improved the results” works. Simply writing “changed the method, improves the results” neither supplies that connection nor preserves the time pattern.

Helping words belong with the verb

Words such as is, was, has, and will can work with another verb word. Count the whole group together when checking whether the sentence is complete.

The scientist has been testing the samples.

Has been testing works together as the main verb. The presence of testing does not make this sentence incomplete.

An -ed word can describe instead of telling the time

Do not decide a word’s job from its ending alone. An -ed word can describe something, while another verb gives the main point.

The samples collected yesterday are ready.

Collected yesterday describes the samples. Are is the main verb. Compare “The team collected the samples,” where collected is the main past action.

Check the exact pattern around the blank

Some verbs need a particular form after them: planned to test, enjoyed testing, or could test. Actions joined by and can also share a subject and use matching forms.

The painter applied color and suspended the canvas.

Applied and suspended are two connected past actions. This is correct: and joins them. The rule is not “only one verb in the whole sentence.”

Do not reject every -ing choice or every sentence with two action words. Check what each word is doing.

v.Use the time clues

Look for a clear time clue

Dates and words such as yesterday, now, and tomorrow help you choose the time of an action. Nearby verbs can help too, but different events may happen at different times.

In 1924, the researcher published her findings.

The date places the publishing in the past. Published fits that completed action.

Use has or have for a past action connected to now

Has or have can describe something that began earlier and continues now, or something completed at an unspecified time with a present connection. Use a form that fits the actual time clue.

Since 2018, the team has monitored the river.

Since 2018 links the earlier starting point to now. Has monitored fits the continuing record of work.

Had can mark an earlier past action

When the sentence looks back from one past moment to an even earlier action, had + the appropriate verb form can make that order clear. Do not add had just because something happened long ago.

By the time the inspection began, the team had repaired the sensor.

Repairing happened before the inspection began. Had repaired makes that earlier step clear.

Keep facts and reports in their own time

A past discovery can lead to a statement that is still true now. The sentence does not need every verb to have the same time.

The study showed that this metal expands when heated.

Showed reports a past study. Expands states the general fact. The change in time has a reason.

Longer verb forms are not automatically wrong. Use the time clues to decide.

’sChoose what refers back correctly

Find the word being referred to

Before choosing it or they, ask exactly what the word refers to. One thing usually takes it; several things take they. Check the intended meaning rather than the nearest noun. They can also refer to one person; the verb still follows “they are” or “they have.” Words such as this and that can refer to a whole earlier event or idea when the meaning is clear.

The researchers adjusted the device because it was overheating.

It refers to the device, not the researchers. There is one device. Compare “The bridge closed. This delayed traffic”: this clearly refers to the bridge’s closing, an event described by the whole preceding sentence.

Match ownership to the owner

Its and their show ownership. Choose based on who owns or has the thing, not on how many things are owned.

The birds returned to their nests.

The nests belong to the birds, so their fits. The word birds tells us the owners are plural.

Try the sentence with just one person

For choices such as I/me or she/her in a pair, temporarily remove the other person. Try the sentence with just the word being tested. After words such as to, for, or with, use me, him, her, us, or them.

The guide spoke to Maya and me.

Try “The guide spoke to me.” That works; “to I” does not. Put Maya back afterward.

Use a simple swap for who and whom

When these choices appear, try he/she/they or him/her/them in the smaller part being tested. Who fits the first group; whom fits the second. Read the whole smaller part, not just the word immediately before the blank.

The artist whom we interviewed thanked us.

We interviewed him or her, not he or she, so whom fits. You can solve this with the swap without learning a new grammar name.

Check words that point back to the same person

Use myself, herself, themselves, and similar forms when the action points back to the same person or when the word adds emphasis. Do not use them just because they sound formal.

The artist introduced herself. / The artist herself answered.

In the first sentence, the artist introduces the same person: herself. In the second, herself emphasizes that the artist personally answered.

Do not change a clear reference just because another noun is closer to the blank.

;Put descriptions next to the right thing

After an opening description, name what it describes

When an opening description leaves the person or thing it describes unnamed, the following main subject should name that person or thing. “Carrying a stack of books” does not name who is carrying them, so check the main subject next. An opening part that names its own subject is different: “While Mina carried the books, the door swung shut” already tells us that Mina carried them.

Carrying a stack of books, Mina entered the room.

Who was carrying the books? Mina. Her name follows the opening description.

Check what the sentence accidentally describes

An answer can mention the right person later and still start with the wrong subject. Read the opening description straight into the first main subject.

Carrying a stack of books, the door slammed behind Mina.

The next main subject is “the door,” so the sentence wrongly makes the door the carrier. Mina appears later, but that does not make her the subject. Start with the person doing the carrying: “Carrying a stack of books, Mina entered as the door slammed behind her.”

Keep other descriptions close too

A description later in the sentence should clearly attach to the right person or thing. Follow the meaning and choose an order that avoids confusion.

The scientist examined a leaf covered in tiny spots.

Covered in tiny spots describes the leaf. It sits beside leaf, where the connection is clear.

Seeing the right name somewhere in an answer is not enough. Check the actual subject after the description.

→Connect ideas

Summarize both sides before choosing

Closely read the part before the blank and summarize its main point in a few words. Then closely read the part after the blank and summarize that point separately. Ask how the second part connects to the first. Only then choose a transition with that meaning. The two parts can be whole sentences or parts of one sentence.

Before: a turtle’s shell looks external. After: people mistakenly think it is an outer skeleton. Relationship: the appearance causes the mistaken belief. Choice: “Hence” (= as a result).

Your two summaries should preserve what each part actually says. Here the second part describes a belief caused by the appearance. A later correction does not change the relationship right at the blank.

An example is one case of a bigger idea

“For example” introduces one case that shows a broader point. “Specifically” narrows a statement to a precise detail. “In other words” restates the same idea more clearly. Ask whether the next sentence gives a case, a detail, or a restatement.

Several birds thrive in cities. For example, peregrine falcons nest on tall buildings.

Peregrine falcons are one case supporting the broader statement about several birds. A new fact about birds is not automatically an example.

Addition and similarity are different connections

“In addition” adds another relevant point. “Similarly” compares two cases that work in a similar way. To use “similarly,” you should be able to say what the two cases share. “In fact” often adds a stronger or revealing detail that backs up the preceding claim.

The first material resists heat. Similarly, the second material stays stable at high temperatures.

The two materials share a property. If the second sentence instead gave a different benefit of the first material, an addition would fit better.

A contrast can correct an expectation

“However,” “nevertheless,” and “even so” often introduce something different from what the first idea leads us to expect. Read for the meaning: two sentences can be about the same thing and still point in different directions. “Granted” admits a point before the writer develops a different one.

The route was difficult. Nevertheless, the team finished ahead of schedule.

A difficult route might suggest a slow finish. Finishing early goes against that expectation. Look at the surrounding sentences to see whether the writer is making the main contrast or first admitting a point.

A result needs a reason; a purpose needs a goal

“Therefore,” “consequently,” and “as a result” say that one idea leads to another. “To that end” introduces an action taken to achieve a stated goal. The passage must establish that connection; one event simply happening after another is not enough.

The team wanted clearer images. To that end, it installed a new camera.

The new camera is a step toward the stated goal. If the next sentence described what the camera made possible, a result transition could fit.

Time words tell you when or how often

“Then” and “subsequently” move to a later event. “Previously” looks back. “Meanwhile” usually connects events happening at the same time. “Again and again” means something happened repeatedly. Use dates and time clues to choose the right direction. Check the meaning of “then”: it can also mean “in that case,” introducing a logical result rather than a later event.

The team tested the design in May. Subsequently, it built the final version in August.

The events are in time order. If the passage instead describes repeated tests over many years, a word showing repetition may be more precise.

Check the exact sentence beside the blank

Read enough on each side of the blank to understand the complete ideas. Keep words such as “not,” “rarely,” “may,” and “wasn’t always” in your summaries—they can change the relationship. Compare the summaries, choose the best match, and reread the transition in place. If the surrounding context changes your first interpretation, revise the summaries.

The lake is now protected. That was not always the case. Previously, waste flowed into it unchecked.

The last sentence explains the earlier situation. Although past and present differ, “previously” states the connection to the sentence immediately before it.

All transition choices

This reference covers all 109 distinct choices in the current official transition bank, including longer phrases. Read each meaning and example; categories show the main use, but some words have more than one meaning. You do not need to memorize the whole list before practicing.

109 choices · grouped by meaning

Add another point9
Additionally

Adds another relevant fact, reason, or benefit to the point already made.

The new windows reduce street noise. Additionally, they help keep the rooms warm.

Besides

Adds another reason or consideration, often to strengthen a decision or opinion.

Let's take the train because it is faster. Besides, we will avoid paying for parking.

Watch for: In a phrase such as 'besides the cost,' it means 'in addition to the cost'; do not confuse it with 'beside,' meaning next to.

Beyond the simple coining of a term

Moves from inventing a word or phrase to another, broader contribution.

The guidebook introduced a new name for the hiking route. Beyond the simple coining of a term, it encouraged visitors to explore the area.

Watch for: The earlier part must mention naming or inventing a term; the next part should add something beyond that contribution.

Further complicating these issues

Adds a fact that makes the problems or questions already mentioned harder to resolve.

The organizers faced a small budget and a crowded schedule. Further complicating these issues, the venue announced that it would close for repairs.

Watch for: The earlier part must establish issues, and the new fact must add difficulty rather than merely provide an answer.

Furthermore

Adds another point that develops or strengthens the same overall case.

The proposed park would provide space for exercise. Furthermore, its trees would shade the surrounding streets.

Watch for: A new supporting point differs from a specific example or a restatement of the same point.

In addition

Adds another fact or supporting point alongside the one already given.

The library lends books and magazines. In addition, it offers free language classes.

In addition to these factors

Introduces something to consider alongside the influences or conditions already listed.

Rainfall and sunlight affect how fast the plants grow. In addition to these factors, soil quality matters.

Watch for: A conclusion reached from the listed factors is not itself another factor.

Moreover

Adds another point that supports or develops the same general discussion.

The new windows reduce street noise. Moreover, they keep the rooms warmer in winter.

Watch for: The new point should add information; if it explains the same point in different words, a clarification may fit better.

What’s more

Adds another relevant point, often giving extra weight to the point already being made.

The community pool offers free swimming lessons. What’s more, it lends equipment to beginners.

Watch for: The next part should contribute another point rather than merely translate the previous one into simpler words.

Give an example2
For example

Introduces a particular case that illustrates the broader point before it.

Some plants store water in their leaves. For example, aloe has thick leaves that hold moisture.

Watch for: Check that the specific case really belongs under the earlier general claim.

For instance

Gives one specific illustration of the idea just stated.

The community center offers activities for beginners. For instance, its pottery class requires no previous experience.

Watch for: It works much like 'for example'; the important question is whether the second part illustrates the first.

Explain or be more precise5
In other words

Restates the same main idea in a clearer or different way.

Only residents of the town may enter the contest. In other words, you must live in the town to take part.

Watch for: The meaning should stay consistent; a new example, result, or opposing claim is not a restatement.

In particular

Focuses attention on one specific part, case, or detail within a broader topic.

The team reviewed several parts of the building. In particular, it examined the roof for leaks.

Watch for: It singles something out for attention; it does not merely introduce the next step in a process.

Specifically

Narrows a broad statement by supplying exact details about what it means or how it happened.

The school made the entrance easier to use. Specifically, it installed a ramp beside the steps.

Watch for: An example illustrates a broader claim; 'specifically' gives a more precise account of the matter already being described.

That is

Explains the same point more clearly by restating it or spelling out what it refers to.

The club meets fortnightly. That is, its meetings take place every two weeks.

Watch for: The two parts should express the same underlying information, not two separate examples or actions.

To be exact

Replaces a broad or approximate description with a precise detail.

The walk takes just under an hour. To be exact, it takes fifty minutes.

Watch for: Look for increased precision about the same subject, rather than an unrelated fact.

Strengthen or confirm a point3
Confirming this hypothesis

Introduces evidence presented as supporting the proposed explanation or prediction already mentioned.

The students predicted that warmer water would dissolve the sugar faster. Confirming this hypothesis, their tests showed shorter dissolving times in warmer water.

Watch for: Identify the exact prediction being supported; a related discovery may weaken it instead, and support does not always settle a question forever.

In fact

Introduces a fact that strengthens, makes more precise, or sometimes corrects the preceding idea.

The hall can hold a large audience. In fact, it has seats for two thousand people.

Watch for: It can reinforce a claim or correct an impression; do not assign it one relationship without reading both parts.

Indeed

Often strengthens or confirms the preceding point with a more forceful statement or supporting detail.

The storm caused serious damage. Indeed, it destroyed the roof of the largest building.

Watch for: It can sharpen a claim, as in “not merely useful; indeed, essential.” It can also acknowledge a point before a limitation follows; read both parts.

Show a similar pattern3
Drawing a similar conclusion

Introduces someone reaching a conclusion like the one already described.

One research team concluded that the marsh needed more protection. Drawing a similar conclusion, a second team recommended limiting construction nearby.

Watch for: Compare the conclusions themselves; studying the same topic does not mean reaching similar conclusions.

Likewise

Connects a second case that shares the relevant feature, action, or pattern of the first.

The first poem connects rain with sadness. Likewise, the second uses storms to express grief.

Watch for: Name the shared feature before choosing it; mentioning two poems or two people is not enough.

Similarly

Shows that a second example or situation follows a pattern like the first.

One teacher uses songs to help students remember new words. Similarly, another uses rhymes to make vocabulary memorable.

Watch for: Compare what the two parts say, not just their subject matter; they must share a relevant pattern.

Show a difference or correction12
Actually

Introduces what is really true, often correcting an earlier belief or making a surprising point.

We thought the sculpture was made of stone. Actually, it was carved from wood.

Watch for: It can also emphasize a surprising fact without directly correcting a claim; read what the second part does.

By comparison

Judges one thing against another, often showing how much they differ on the same feature.

The first suitcase weighs eight kilograms. By comparison, the second weighs only three.

Watch for: Look for a shared feature being compared; comparison can reveal similarity as well as difference.

By contrast

Introduces a clear difference between the thing just described and another thing.

The northern slope receives little direct sunlight. By contrast, the southern slope stays sunny for much of the day.

Contrary to this phenomenon

Introduces something that conflicts with the observed event or pattern just described.

Most samples expanded when heated. Contrary to this phenomenon, one sample became slightly smaller.

Watch for: A phenomenon is what happens; challenging an explanation of why it happens is a different relationship.

Conversely

Introduces an opposite or reversed situation in a comparison.

A wider opening lets more light into the box. Conversely, a narrower opening lets less light in.

Watch for: Look for a meaningful reversal; two unrelated differences do not automatically fit.

However

Introduces a difference, limitation, or point that pushes against the preceding idea.

The jacket is very warm. However, it is too bulky to pack easily.

Watch for: It need not introduce a total opposite; a limitation can fit. In 'however hard she tried,' it means 'no matter how.'

In comparison

Describes something in relation to another thing used as a reference point, often highlighting a difference.

Last year's class had thirty students. In comparison, this year's class has just eighteen.

Watch for: Compare the same feature across the two cases; a comparison can also show that they are similar.

In contrast

Highlights how the next case differs from the one before it.

The morning class works in small groups. In contrast, the afternoon class meets as one large group.

In reality

Introduces the actual situation, often correcting how something appears or what someone assumes.

From a distance, the lake appeared shallow. In reality, its center was more than fifty meters deep.

Watch for: Look for an appearance, belief, or expectation that the actual facts change.

On the contrary

Rejects a claim or expectation by stating that the opposite is true.

Some feared the new rule would slow the process. On the contrary, it made the process faster.

Watch for: It is stronger than merely adding a different viewpoint: the second part pushes back against the first claim or expectation.

On the other hand

Introduces a different side or competing consideration, while allowing both points to be true.

The apartment is close to my office. On the other hand, its rent is high.

Watch for: It does not require the words 'on the one hand' earlier, and it does not necessarily correct a false statement.

Undermining this explanation

Signals that the next finding weakens the proposed explanation just given.

Observers suggested that wind alone moved the floating marker. Undermining this explanation, a researcher found that the marker also moved in perfectly still air.

Watch for: Identify the explanation being challenged; weakening a proposed cause does not deny that the observed event happened.

Say “even so” or admit a point14
Admittedly

Acknowledges a fair point or limitation, often one that makes the writer's main position less simple.

The new bus route would serve more neighborhoods. Admittedly, the trip would take longer.

Watch for: The acknowledged point can appear before or after the main claim; it does not mean the writer gives up that claim.

All the same

Means despite what was just said; the next point remains true even though the first might suggest otherwise.

The forecast called for light rain. All the same, we decided to hold the picnic outdoors.

Watch for: As a transition, it means 'even so,' not that two things are identical.

Despite its creation of such an iconic trope

Says that what follows is true even though the work created a widely recognized story pattern or device.

The novel introduced a plot device that later writers used widely. Despite its creation of such an iconic trope, the novel itself is rarely read today.

Watch for: The passage must establish that the work created the device; using an old tradition or inventing a word is not the same thing.

Despite these estimates

Introduces something true or done even though the earlier estimates suggest a different expectation.

The estimates put the repairs far above the town's budget. Despite these estimates, the council voted to begin the project.

Watch for: The next statement must push against an expectation raised by the estimates, rather than simply report what they say.

Even so

Introduces something that remains true despite the preceding fact.

The puzzle had only twenty pieces. Even so, it took us an hour to finish.

Watch for: Ask what the first fact would normally lead you to expect, then check how the second resists that expectation.

Granted

Accepts a point as fair or true, often before explaining why a larger claim still holds.

The new bike path would be useful to many residents. Granted, building it would require months of roadwork.

Watch for: It acknowledges a complication; it does not signal a result or merely add a neutral fact.

Nevertheless

Introduces something that is true or happens despite the fact just stated.

The trail was steep and muddy. Nevertheless, the hikers reached the summit.

Watch for: Ask why the first fact might make the second unexpected; ordinary differences may need a simpler contrast.

Nonetheless

Means 'despite that' and connects an obstacle or limiting fact with something that remains true.

The room was small. Nonetheless, it held everything we needed.

Watch for: It has much the same meaning as 'nevertheless'; check for a real 'despite that' relationship.

Of course

Presents a fact as expected or easy to accept, often acknowledging a limit before continuing the main point.

This indoor garden brings a little nature into the station. Of course, it cannot replace a full outdoor park.

Watch for: It can simply emphasize something expected; look at the surrounding sentences to see whether it introduces a limitation.

Regardless

Shows that an action or conclusion holds without being changed by the fact just mentioned.

The forecast warned of light rain. Regardless, the organizers kept the outdoor event on the schedule.

Watch for: Ask what fact is being set aside; it does not merely add another supporting example.

Still

As a transition meaning 'even so,' introduces a point that remains true despite the preceding fact.

The instructions were brief. Still, they gave us enough information to finish the task.

Watch for: In 'She still works there,' it instead means that an earlier situation continues; this is different from simply saying 'currently.'

That being said

Acknowledges the preceding point, then adds a qualification or a consideration that pulls in another direction.

The plan would save money. That being said, it would require more volunteer time.

Watch for: It usually limits or balances the earlier point rather than restating it or presenting a result.

That said

Means 'having acknowledged that': it introduces a point that qualifies or balances what came before.

The model leaves out several details. That said, it gives a useful picture of the basic process.

Watch for: The first statement can remain true; the second explains why it is not the whole story.

Though

As a transition meaning 'however,' qualifies the preceding statement with a contrasting point.

The two bags look identical. One, though, holds twice as much as the other.

Watch for: It can appear inside or at the end of the second sentence; compare the whole ideas on either side of the blank.

Offer or choose another possibility3
Alternatively

Offers a different option or possible explanation to consider.

We could take the train to the museum. Alternatively, we could ride our bikes.

Watch for: An alternative is a different possibility, not simply the next event or another supporting detail.

Instead

Shows that one action, result, or idea takes the place of another that was considered or expected.

We expected the team to build a new stage. Instead, it repaired the existing one.

Watch for: Find the displaced option or expectation; two different facts do not automatically involve a replacement.

Rather

As a transition, replaces or corrects an idea with a better description of what is true.

The sculpture is not made from stone. Rather, the artist shaped it from recycled plastic.

Watch for: In 'rather cold,' it means 'somewhat'; in 'would rather,' it expresses preference, so do not apply the transition meaning everywhere.

Show a result or conclusion14
Accordingly

Introduces an action or conclusion that follows from the situation just described: because of that, or in a way that fits that situation.

The trail was covered in ice. Accordingly, the hikers chose a safer route.

Watch for: The first part should explain the response in the second; two events happening in order is not enough.

As a result

Introduces an effect produced by the event or situation before the blank.

Heavy rain flooded the field. As a result, the match was postponed.

Watch for: Check the direction: the first part gives the cause, and the second gives the effect.

As such

Links what follows to the role, quality, or situation just described: in that role, or because that is the case.

Maya is the team's elected captain. As such, she represents the team at league meetings.

Watch for: Ask what 'such' points back to; it can connect a situation to its implication, but it is not a substitute for every use of 'therefore.'

Based on these models

Says that the models already mentioned provide the basis for the next estimate or conclusion.

The engineers built computer models of the bridge under heavy loads. Based on these models, they estimated how much weight the bridge could support.

Watch for: This phrase needs earlier models; it connects evidence to a finding, not necessarily a physical cause to an effect.

By achieving such a lofty goal

Says that reaching the ambitious goal already mentioned brought about the next result.

The town aimed to power every public building with sunlight and reached that target. By achieving such a lofty goal, it greatly reduced its use of fossil fuels.

Watch for: There must be an ambitious goal, and the passage must support that it was achieved; an impressive result alone does not show that it was intended.

Consequently

Introduces a consequence of the preceding event, condition, or reasoning.

The store ran out of flour. Consequently, the bakery could not make its usual bread.

Watch for: The consequence must follow from the first part; a detail explaining that first part runs in the other direction.

For this reason

Points to the earlier statement as the reason for the next action or conclusion.

The fabric fades quickly in sunlight. For this reason, the museum keeps it away from windows.

Watch for: You should be able to name the reason supplied before the blank.

Hence

Introduces a result or conclusion that follows from what was just said.

The painting lacks the artist's usual signature. Hence, experts are investigating who made it.

Watch for: In an expression such as 'two years hence,' it means two years from now; that is a different use.

In doing so

Links the action just described to something accomplished through that action or happening as part of it.

The students compared several accounts of the event. In doing so, they noticed details that only one witness mentioned.

Watch for: Identify the action that 'doing so' refers to; the next sentence must connect to performing that action.

In response

Introduces an action or change prompted by the situation just described.

Visitors said the map was hard to read. In response, the museum printed a larger version.

Watch for: Look for a situation followed by a reaction to it; a later event alone is not enough.

In so doing

Means 'by doing that': the action before the blank also produces the effect after it.

The club planted trees beside the playground. In so doing, it created shade for the swings.

Watch for: The second effect must come through the action already described, not merely happen afterward.

In turn

Often introduces the next effect in a chain: one change leads to another, which leads to the next.

The new bus route brought more visitors to the market. This, in turn, increased sales at nearby shops.

Watch for: It can also mean 'one after another,' as when speakers take turns; use the surrounding ideas to decide.

Therefore

Introduces a result or conclusion that follows from the reason or evidence before the blank.

Every available room is already booked. Therefore, the meeting must take place elsewhere.

Watch for: Check the direction: the first part supplies the reason, and the second gives what follows from it.

Thus

Often means 'therefore,' introducing an effect, conclusion, or prediction supported by what came before.

The container is too wide for the opening. Thus, we cannot move it through that doorway.

Watch for: It can also mean 'in this way'; decide whether the passage points to a conclusion or to a method.

Connect a goal or action1
To that end

Means 'to achieve that goal' and connects a stated aim with an action taken to pursue it.

The school wanted more students to join the reading club. To that end, it scheduled meetings during lunch.

Watch for: Identify the goal before the blank; an action serving a goal does not prove that the goal was achieved.

Place events in time16
After

Places an event later than a named time or another event.

The students spent the morning drawing. After lunch, they painted their sketches.

Watch for: Usually name what comes before, as in 'after lunch' or 'after the rain stopped'; 'afterward' can mean later on its own.

Afterward

Introduces something that happens later than the event just described.

The audience watched the short film. Afterward, the director answered questions.

Watch for: Later does not automatically mean caused by the earlier event.

Currently

Locates a situation in the present, or at the time being discussed.

The theater once served as a warehouse. Currently, it hosts plays and concerts.

Watch for: It tells when something is true; it does not by itself explain a cause or a comparison.

Earlier

Moves to a time before the event or period just mentioned.

By noon, the road was clear. Earlier, fallen branches had blocked both lanes.

Watch for: Track the timeline: the sentence after 'earlier' goes backward in time.

Eventually

Introduces what happens after some time, effort, or intervening events.

The volunteers searched the park for several hours. Eventually, they found the missing dog.

Watch for: It means in the end after a stretch of time, not merely possibly.

In the end

Points to how a process or situation finally turns out, often after changes or uncertainty.

We considered taking the train and then looked at bus routes. In the end, we decided to walk.

Watch for: This usually marks a final outcome, not simply the last point a writer happens to mention.

Increasingly

Shows that something is becoming greater, stronger, or more common as time passes.

Few students used the study room when it opened. Increasingly, they are choosing it for group work.

Watch for: It describes growth over time, not just something happening often or an additional fact.

Later

Places an event after the time or event already mentioned.

The group toured the garden in the morning. Later, it visited the greenhouse.

Watch for: It shows time order without explaining a cause or naming a location.

Meanwhile

Usually shifts to something happening during the same period; it can also turn to a separate situation being compared.

The bread baked in the oven. Meanwhile, Sam prepared the soup.

Watch for: It need not mean the exact same instant, and in some passages the main point is a contrast between parallel situations.

Nowadays

Refers to the present period, often to show how a current practice differs from an earlier one.

The club once mailed paper newsletters. Nowadays, it sends updates by email.

Watch for: It means 'these days,' not 'at the next moment' in a story about the past.

Previously

Looks back to a time before the situation or event under discussion.

The library began opening on Sundays last year. Previously, it was closed that day.

Watch for: The earlier time is measured from the event being discussed, which may itself be in the past.

Soon

Places an event a short time after the present moment or another time already mentioned.

The rain stopped just after lunch. Soon, children returned to the playground.

Watch for: The passage must support a short time gap; a detailed explanation of an earlier event is not necessarily a later event.

Subsequently

Means afterward: an event takes place later than the event just described.

The town approved the design in March. Subsequently, workers began building the bridge.

Watch for: Time order alone does not prove cause and effect, and this word does not say the gap was short.

Then

Often moves to a later event or next step; it can also mean 'in that case' and introduce a conclusion.

For years, the building stood empty. Then, a community group converted it into a theater.

Watch for: In “If the door is locked, then we need another entrance,” it draws a conclusion; in “back then,” it points to a past time.

Today

Refers to the current day or, in a broader account, to the present period.

The building once housed a factory. Today, it serves as a public library.

Watch for: Historical comparisons often use it to mean 'in the present day,' not one particular calendar date.

Ultimately

Points to a final outcome, or to the deepest goal or consideration behind an action.

The team first tried to repair the old machine. Ultimately, it decided to replace it.

Watch for: It can point to a larger purpose, such as winning political support, without describing an event that happens later.

Put points or steps in order12
Alternately

Usually means taking turns or switching back and forth; it can also introduce another option.

The warning light switches between two colors. It glows alternately red and green.

Watch for: Distinguish repeated switching from offering a choice; 'alternatively' clearly means another option.

Finally

Marks the last step or point, or something that happens after a wait.

We measured the wood and cut the pieces. Finally, we assembled the shelf.

Watch for: It may end a list or describe an event at last; it does not always summarize an argument.

First

Marks the beginning of a series of steps, events, or points.

The recipe has three main steps. First, mix the flour and water.

Watch for: It may organize an explanation or identify what happened earliest; use the surrounding passage to tell which.

First of all

Introduces the first point to consider or the first action to take, sometimes giving it special priority.

Several changes could improve the playground. First of all, the broken gate needs repair.

Firstly

Introduces the first item in an organized list of points or reasons.

The larger room suits our club for two reasons. Firstly, it has enough chairs for everyone.

Watch for: A first listed reason need not be an event that happened first in time.

In the first place

Introduces a first reason or point; it can also refer back to an original situation or reason.

There are two reasons to keep the old bridge. In the first place, it is still safe to use.

Watch for: In 'Why was it built in the first place?' the phrase means 'originally,' not 'first on a list.'

In the second place

Adds the second point in an ordered set of reasons or arguments.

In the first place, the evening class fits my schedule. In the second place, it covers the topic I need.

Watch for: Look for a first point already established; an example explaining that first point is not necessarily a second point.

Lastly

Introduces the final item, point, or step in a series.

First, rinse the jar, and next, dry it. Lastly, put the lid back on.

Watch for: A final listed step differs from an event that merely occurs later in history.

Next

Moves to the following step, event, or point in an ordered series.

First, fold the paper in half. Next, draw a line along the fold.

Watch for: A detail explaining the current step does not necessarily move to a new step.

Second

Introduces point or step number two in an ordered series.

First, check that the box contains all the pieces. Second, arrange them by size.

Watch for: As a transition, it orders ideas or actions; it does not explain why the second one happens.

Second of all

Adds the second reason or point after a first one has been established.

First of all, the proposed meeting time conflicts with class. Second of all, the room is already booked.

Watch for: The next statement needs to function as another listed point, not a correction to the first.

Secondly

Marks the second item in an ordered explanation, argument, or set of instructions.

Firstly, the route is shorter. Secondly, it avoids the busiest roads.

Watch for: The first point need not literally begin 'firstly,' but there should be an ordered set of points.

Say how often or how much5
Again and again

Says that an event or pattern happens repeatedly.

The team tested the same design on several days. Again and again, the bridge model held the full weight.

In many cases

Says that something is true in numerous situations, without claiming it is true in all of them.

The volunteers tried several ways to repair the torn pages. In many cases, a small strip of paper was enough.

Watch for: Many does not necessarily mean most or all; this phrase limits how broadly the statement applies.

Intermittently

Means that something happens on and off, with breaks between occurrences.

The porch light did not shine steadily. Intermittently, it flickered on before going dark again.

Watch for: It does not mean continuously, and it does not promise evenly spaced intervals.

More often

Shows that one event or pattern happens more frequently than another, or more frequently than before.

Customers occasionally order a whole cake. More often, they buy a single slice.

Watch for: Identify what frequency is being compared; unlike 'increasingly,' it does not always describe a trend over time.

Sometimes

Means on some occasions or in some cases, without saying that it happens every time.

The library usually hosts talks in its main hall. Sometimes, it uses the courtyard instead.

Watch for: It does not specify an exact frequency or necessarily mean that something is rare.

Sum up or finish4
In conclusion

Signals a closing statement that sums up the discussion or gives its final judgment.

The trial showed that the new bag was lighter, stronger, and easier to carry. In conclusion, it met all three design goals.

Watch for: A new example or a conflicting discovery is not automatically a conclusion just because it comes last.

In sum

Pulls the preceding points together into a brief overall statement.

The tent is light, simple to assemble, and easy to carry. In sum, it is well suited to short hiking trips.

Watch for: A final sentence may add a new detail instead of summarizing, so position alone does not make this fit.

In summary

Signals a short recap of the main information already given.

The workshop covers planning, drafting, and revising. In summary, it teaches the main stages of writing.

Watch for: Check that the second part gathers earlier information rather than introducing a new step or example.

To conclude

Signals that the writer is closing the discussion with a final overall point or judgment.

The route is short, well marked, and close to town. To conclude, it is a practical choice for our afternoon walk.

Watch for: It need not repeat every detail, but merely appearing in the last sentence does not make it appropriate.

Refer to a place2
Elsewhere

Moves to a different place or a different part of a text.

The eastern valley received heavy rain. Elsewhere, the ground remained dry.

Watch for: A location must change; a new point about the same place is not enough.

There

Points back to a place already mentioned and locates the next action in that place.

The team carried the samples to the laboratory. There, researchers examined them under a microscope.

Watch for: Find the place it refers to; 'there' in 'there are three samples' serves a different purpose.

Connect to a particular situation4
Fittingly

Shows that the next detail is appropriate or makes sense given what came before.

The scientist spent her career studying stars. Fittingly, the observatory named its new telescope after her.

Watch for: The emphasis is on how well the detail suits the situation, not just on one event causing another.

In any case

Introduces a point that holds regardless of the possibilities or uncertainty just discussed, or returns to the main point.

The train may arrive at six or at seven. In any case, someone will be there to meet it.

Watch for: The next point should hold either way; it need not be a result of the first possibility.

Ultimately limited in its lasting influence

Describes something as having only a small effect in the long run; it makes a claim about the subject that follows.

A local exhibition briefly attracted attention but inspired few later artists. Ultimately limited in its lasting influence, the exhibition remained a footnote in the town's history.

Watch for: This is a description fitted to a particular passage, not a fixed transition. It does not fit if the passage emphasizes lasting contributions.

With this in mind

Shows that the next action or judgment takes the previously stated fact, concern, or goal into account.

Many visitors arrive with young children. With this in mind, the museum placed its activity tables near the entrance.

Watch for: It can connect an action to a goal, but the earlier idea may also be a fact or constraint rather than a stated aim.

Do not choose from a transition’s familiar sound or the passage’s general topic. A summary that drops “not,” “rarely,” or another key word can lead to the wrong relationship.

→Use notes to answer the task

Keep coming back to the exact task

Read the task closely before reading the notes. Turn every requirement into a short checklist: what must the answer do, what must it discuss, and who is the audience? Reread the task as you compare choices and once more before choosing. Pick the answer that fulfills all parts as directly and completely as possible.

Task: describe a chair to readers unfamiliar with its maker. Checklist: (1) Describe the chair. (2) Introduce the maker. An answer that does only one part is incomplete.

A true fact, a relevant detail, or a sentence that answers only part of the task is not enough. The best choice must match the whole request.

Use the relevant notes; you do not need all of them

Use the notes that help fulfill the task. You do not need every note, but you do need every part of the request. A short answer can be complete; a long one can miss the point. When two choices seem useful, reread the task and identify which one meets its requirements more directly or fully.

Task: identify the material used for a chair. Notes also give its maker’s birthplace and awards. → Choose the sentence that identifies the material.

More facts do not automatically make an answer better. The required information controls the choice, not its length.

Compare the exact thing the task names

For a similarity, find a shared feature and connect it to both subjects. For a difference, directly show how the subjects differ on the requested feature. If the task asks about research results, comparing the researchers’ locations will not do.

One group detected scents at 8 meters; another detected them at 3 meters. → The first group detected scents from farther away.

The comparison makes the difference explicit. Merely naming both groups or listing unrelated facts does not emphasize that difference.

Separate why a study happened, how it worked, and what it found

An aim is what researchers wanted to learn. A method is what they did to investigate it. A result is what they found. Match the answer to the part the task requests.

Aim: learn whether shade helps seedlings. Method: grow seedlings in sun and shade. Result: shaded seedlings grew taller.

A result cannot replace the study’s aim, even when both statements are accurate. “Wanted to find out” often points to an aim; measurements and procedures often describe the method.

Give the audience the introduction it needs

Treat the audience as part of the task. If readers do not know a person, work, or term, the answer may need a brief introduction as well as the requested detail. An answer that describes the work but never identifies its unfamiliar creator can miss half the request. If readers already know the topic, focus on the information the task asks you to emphasize.

Task: describe a chair to readers unfamiliar with its maker. → Introduce the maker as a furniture designer and describe the chair.

Describing only the chair can miss the audience requirement. Giving only the maker’s biography can miss the requested description.

Keep every claim faithful to the notes

Check who did what, which number belongs to which subject, and the order of events. Do not turn “helped pass a law” into “passed the law,” or one example into a claim about every case. An answer can sound useful and still misstate a fact.

The organization urged Congress to pass a law. Congress passed it. → The organization helped bring about the law; it did not pass the law itself.

The roles matter. A choice that answers the right kind of question with a false claim must be eliminated.

Match the strength of the claim to the evidence

A generalization states a broader pattern supported by particular examples. If the task asks you to make and support it, include both the pattern and evidence or a reason. An example illustrates a point; a conclusion states what the evidence lets us say. Avoid unsupported causes, opinions, or “always” claims.

The notes describe two insects whose wings imitate leaves. → Some insects have wings that resemble leaves.

The notes support a statement about some insects. They do not show that all insects resemble leaves or prove why the feature developed.

Being true is not enough. An answer may address the wrong goal, leave out one part, or do the requested job less clearly than another choice. Reread the task to decide.
