Petty (adjective): concerned with small, unimportant details or matters, especially in a way that shows resentment or spite; also, something minor or trivial.
This word describes behavior or feelings focused on tiny things that really don’t matter much, often because someone feels slighted. It’s like getting upset over a minor issue while ignoring bigger problems — the resentment makes the small stuff feel huge.
The core meaning is small-minded or trivial. When people call someone petty, they’re saying the person is holding grudges or arguing over insignificant details, often out of spite. It can also just mean something is minor in scale, like petty cash for small expenses.
In everyday life, “petty” has a negative shade when describing people — it signals immaturity or unwillingness to let go. We use it to criticize holding onto small slights, like in arguments or social drama. The word highlights how focusing on the little stuff can make someone seem small-hearted.
