IDK stands for I don't know, a texting and chat abbreviation.

Admits a lack of knowledge or indecision, and is the classic chat answer to questions like "what do you want to eat?" Used by every age group.

Example: Idk, maybe pizza? You choose this time, I chose last week.

Usage notes

Pronounced as letters. Linguists note that "idk" often works as a softener or hedge, letting the writer avoid committing to an answer. Variants include IDEK (I don't even know) and idrk (I don't really know). Fine in informal work chat; spell it out in emails and formal writing.
