Conversation

Have you heard about Sam? I think he's becoming an underachiever this semester.

Yeah, I noticed he hasn't been putting in much effort lately.

It's frustrating because he has so much potential.

Totally! I hope he finds the motivation to turn things around.

Root Explanation

Underachiever → It is formed from "under-" (meaning below or beneath) and "achiever" (from the verb "achieve", which comes from Old French *achever*, meaning to complete or bring to a conclusion). The word describes someone who performs below their potential or fails to achieve expected success.

Memory Tip

Think of someone who is performing 'below' ('under-') their full potential to 'complete' ('achieve') their goals — that's what an underachiever means.
