How it's used

Carries a slightly sarcastic or mocking tone when used to describe someone who pretends to know everything. It is often used to call out people who offer unsolicited advice or opinions on topics they do not actually understand. While it can be used neutrally to describe a genuinely knowledgeable person, the context usually implies a sense of annoyance.

Common phrases

to pretend to be a know-it-all

Common mistake

Avoid using this to describe a professional expert or a scholar, as it implies a superficial or arrogant kind of knowledge rather than deep expertise. It is strictly for social contexts where someone is being a bit of a show-off.
