Step by step

ISEE Sentence Completion: Predict the Word with Connectors

Students answer ISEE sentence completion questions most reliably by reading the whole sentence first, finding the connector that links the blank to the rest of the sentence, and predicting the missing word in their own words before looking at the options. Words such as although, however, because and since show whether the blank continues or reverses the idea in the other part of the sentence. This lesson teaches a three-step method, works one original Middle Level question, and explains why each option is right or wrong.

A three-step method

This section explains the routine that works for most sentence completion questions. The question gives a sentence with one word missing, and the task is to choose the option that makes the sentence logical. The routine has three steps, and the order matters.

Step 1: Read the whole sentence and find the connector. The connector is the word or phrase that shows how the blank relates to the rest of the sentence. It is often at the start, as in “Although…” or “Because…”, but it can also sit in the middle, as in “…however, the results were…”. Students should underline it, mentally if the test is on screen.

Step 2: Predict the meaning in your own words. Before reading any option, the student decides what kind of word the blank needs. The prediction does not have to be a single exact word. “Something short and clear” or “a negative word” is enough. A prediction protects the student from choosing a word only because it looks familiar or sounds impressive.

Step 3: Match the prediction to the options. The student then reads all four options and removes any that contradict the connector or the prediction. If more than one option remains, the student reads the sentence again with each option in place and chooses the one that fits both the meaning and the tone.

What the connector tells you

This section lists the relationships most connectors signal. Learning these three groups covers a large share of sentence completion questions.

Relationship Example connectors What the blank usually does
Contrast although, but, however, despite, yet, while Reverses an idea stated elsewhere in the sentence
Cause and effect because, since, so, therefore, as a result Follows logically from a stated reason or result
Continuation and, also, similarly, in addition, moreover Repeats or extends the same idea

A connector is a direction sign. Contrast connectors turn the sentence around, cause connectors point back to a reason, and continuation connectors keep going the same way. A blank that contradicts its connector cannot be correct, regardless of how good the word is in isolation.

Try the example

Work through the question below using the three steps. Read the sentence, find the connector, say the missing word aloud or in your head, and only then choose an option. The explanation appears after an answer is selected.

Why each answer works or does not

This section walks through the example after it has been answered. The connector is “although”, a contrast word. The first part of the sentence says the draft was long and repetitive, so the second part must say the revision was different in a positive way. The prediction is “short and clear”, and the correct option, concise, matches it directly.

Each wrong option fails for a distinct reason, and naming that reason is the habit to build.

  • elaborate continues the problem instead of reversing it. It would suit a sentence joined by “and”, not “although”.
  • outdated is a real word that sounds negative, but nothing in the sentence connects to age or timeliness.
  • anonymous is also a real word, but it belongs to a different topic, the identity of the writer.

Students who review all four options after every practice question, not only the one they chose, learn how test writers build distractors. Wrong options usually fall into three types: the same direction as the clue when the connector requires the opposite, a word on a different topic, and a word that sounds suitable but has no support in the sentence.

Common traps

This section describes two mistakes that cost students points even when their vocabulary is strong.

Being frightened by an unfamiliar word. Many students see a difficult option and conclude the question cannot be solved. The better response is to ignore the unfamiliar word, test the other three against the prediction, and choose the unfamiliar word if the rest fail. A word’s tone also helps: if the sentence needs a positive word and the unknown option sounds harsh, it is probably wrong.

Reading the options before the sentence. A student who sees four options first tends to pick the word that is most familiar and then force the sentence to agree. This reverses the logic of the question. Reading the sentence first, predicting, and then looking at the options keeps the meaning of the sentence in control.

A third habit that helps is to reread the finished sentence with the chosen word in place. A choice that reads awkwardly or changes the meaning of the first half of the sentence is usually wrong.

Your next step

This section suggests how to continue after this lesson. Practice the three steps on a handful of sentences each day, and write down the connector and the prediction for each one before checking the options. Vocabulary study is covered in the synonyms lesson, and the Verbal Reasoning overview explains how both question types fit together. Families who want a mixed set of practice questions with explanations can start with the free trial.

Frequently asked questions

How do students prepare for ISEE sentence completion questions?

Students prepare by practicing one habit: read the whole sentence, find the connector, and say the missing word in their own words before reading the options. Short, regular practice with explanations for every option is usually more effective than long sessions of unreviewed questions.

What are the most useful clue words in sentence completion?

Contrast words such as although, but, however and despite signal that the blank reverses an idea elsewhere in the sentence. Cause words such as because and since signal that the blank follows from a stated reason. Words such as and, also and similarly signal that the blank continues the same idea.

Should students look at the answer choices before reading the sentence?

No. Reading the options first invites students to choose the most familiar word instead of the word the sentence requires. Reading the sentence and predicting a meaning first keeps the sentence in charge, and the options then become a matching exercise.

What should a student do when an answer choice is an unfamiliar word?

Students should compare the remaining options with the prediction first. If three options clearly do not fit, the unfamiliar option is usually the answer. Roots, prefixes and the tone of the word, positive or negative, can also help when the exact meaning is unknown.

Is a wrong answer penalized on ISEE sentence completion questions?

Scores are based on the number of correct answers, so students should answer every question. Eliminating options that contradict the connector first improves the chance of a correct guess when time is short.
