Important examples of assumption in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC word questions, assumption typically refers to a belief or statement taken for granted without proof.

▪She made an assumption about the meeting time.
▪She believed something about the meeting time without proof.

Example of a confusing word: assertion (a confident statement)

▪She made an assertion about the meeting time.
▪She confidently stated something about the meeting time.
"Assumption" is a noun meaning "a belief accepted as true without evidence." In the sentence "She made an assumption about the meeting time," it implies she guessed the time without confirmation. "Assertion," however, means "a confident and forceful statement of fact or belief." Using "assertion" suggests certainty and is not interchangeable with "assumption" in this context. Thus, "assumption" is the correct choice for expressing an unproven belief.
