What does 'it is what it is' mean?

What it means: Acceptance that a situation can't be changed and there's no point fighting it. It signals resignation, pragmatism, or sometimes emotional exhaustion.

"The project failed. It is what it is — we move on."
"I didn't get the promotion. It is what it is."

What it really signals: The speaker has processed the situation and chosen not to dwell. It closes down further analysis or complaint. Sometimes it's genuine wisdom; sometimes it's avoiding a difficult conversation.

Why some people find it frustrating: It can shut down legitimate discussion. "It is what it is" can mean "I don't want to hear your concerns" dressed up as acceptance. Context determines which it is.

• "That's just how it is" — similar
• "Nothing we can do about it" — more explicit
• "Let's move on" — action-focused

Register: Casual. Very common in American and British English.
