Important examples of effective in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC word questions, effective is often used to describe something that works well.

▪The new policy is effective immediately.
▪The new policy starts now.

Example of a confusing word: efficient (performing in the best possible manner with the least waste of time and effort)

▪The new policy is efficient immediately.
▪The new policy operates efficiently from now.
"Effective" means that something is successful in producing a desired or intended result, or it can refer to the point in time when something starts to apply. In the sentence "The new policy is effective immediately," it indicates that the policy is now in force. "Efficient," however, refers to how well something performs with minimal waste. Saying "The new policy is efficient immediately" is grammatically awkward because "efficient" does not describe the timing of when something starts. Therefore, "effective" is the correct choice here.

Grammar examples from the TOEIC test
