How it's used

It is formal enough that you would rarely use it in casual, friendly banter, appearing more often in news reports, legal contexts, or serious arguments regarding professional integrity. Unlike simply saying someone is lying, this word specifically highlights the goal of ruining a reputation.
Examples
Don't go around defaming people behind their backs.
Why would he want to defame your reputation?

Common mistake
Learners often confuse this with general criticism or complaining. It is much more severe than 投訴 or 批評, as it implies the information being spread is intentionally false and damaging.
