What Does IDK Mean in a Text?

So, what does IDK mean in text? It means “I don’t know,” or more exactly, it is an abbreviation of the phrase “I don’t know.” Just to remind you, abbreviations are shorter versions of words created to save you time and space in writing.

Americans, especially the younger population, use IDK when texting or online chatting with friends or family members. Even though it was probably created in 2002, IDK became a popular abbreviation in 2007, and then once again during the global pandemic when people used memes to express their confusion about the whole situation.

When communicating with your friends or family members, you should use it instead of “I don’t know” on social media, texts, chats, or SMS messages. You can either capitalize it or not; it’s really up to you as the meaning will stay the same.

However, in some situations using the capitalized version, IDK, may seem like you’re shouting it or just trying to point it out in the sentence. And, make sure you use this abbreviation only in informal writing.
