TOEFL® Complete the Words: How to Pick the Right Word Every Time

Complete the Words gives you a sentence or short passage with a blank, and a set of word choices that often look deceptively similar. The trap isn't vocabulary size — it's picking a word that's close in meaning but wrong for that exact slot.

Check the grammar slot first

Before thinking about meaning at all, decide what part of speech the blank needs: noun, verb, adjective, or adverb. This alone eliminates answer choices instantly — a word that means roughly the right thing but is the wrong part of speech is always wrong.

Then check collocation

English pairs certain words together by habit, not just logic — "make a decision," not "do a decision"; "heavy rain," not "strong rain." Native-level fluency partly comes from knowing these fixed pairings. When two choices seem equally correct in meaning, the one that "sounds right" together with the surrounding words is usually the answer.

Example
"The committee will _____ a final decision by Friday."
(A) make   (B) do   (C) take   (D) give

All four are common verbs, but only "make a decision" is the standard collocation in English — the others are just wrong pairings, even though "take a decision" is heard in some other varieties of English.

Watch for near-synonyms testing precision

Some questions test the difference between words that mean almost the same thing but carry a different shade of meaning — "big" vs. "significant," "look" vs. "glance." Reread the full sentence with each option substituted in, and ask which one keeps the sentence's exact intended meaning, not just a similar one.

Don't pick the first word that "sounds okay." Read the full sentence with your chosen answer substituted in before moving on — the wrong choice often only reveals itself when you read the complete sentence back.
