Important examples of defective in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC vocabulary questions, defective is often used to describe products or parts that do not work.

▪The item was returned because it was defective.
▪The item was sent back because it was faulty.

Example of a confusing word: effective (producing a desired result)

▪The item was returned because it was effective.
▪The item was kept because it worked well.
"Defective" is an adjective meaning "having a flaw or not working correctly," which is why an item might be returned. In contrast, "effective" means "producing a desired result" or "working well," which is the opposite of defective. Using "effective" in the sentence "The item was returned because it was effective" is logically and grammatically incorrect, as it contradicts the reason for returning an item. Therefore, "defective" is the correct choice when describing an item that is not functioning properly.

Grammar examples from the TOEIC test

Defective is used as an adjective to describe nouns, often appearing in grammar questions to test adjective placement.
