Small-minded

PETTY

Think of how someone might describe a minor or trivial complaint that feels unnecessarily focused on small details.

"Small-minded" hints at someone who focuses on trivial or unimportant things, which perfectly describes "petty." The word can mean both minor in importance (like a petty issue) and narrow in outlook (like a petty person). There’s no hidden wordplay here—it’s a straightforward definition where the clue and answer align directly in meaning. Think of someone who gets upset over small stuff or holds grudges over minor slights.
