Important examples of inefficient in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC vocabulary questions, inefficient is often used to describe processes or systems that waste time.

▪The company found the system inefficient.
▪The company found the system not working well.

Example of a confusing word: insufficient (not enough)

▪The company found the system insufficient.
▪The company found the system lacking enough resources.
"Inefficient" is an adjective meaning "not achieving maximum productivity" or "wasting resources." In the sentence "The company found the system inefficient," it correctly describes a system that does not work optimally. "Insufficient," however, means "not enough" or "lacking," and while it can describe a system, it refers to quantity rather than performance. Saying "the system insufficient" without specifying what is lacking is grammatically incomplete and shifts the focus from performance to quantity. Therefore, "inefficient" is the correct choice for describing poor performance.

Grammar examples from the TOEIC test

Inefficient is used in grammar questions to compare with efficient, often in discussions about productivity.

▪The process was inefficient compared to the new one.
