Quick Answer:

What Does Alt Mean in Text?

In texting and online slang, “alt” is short for “alternative.”

Its meaning depends heavily on the context:

1. Alternative personality or identity: Many people use “alt” to describe a side of themselves that’s different from their usual persona. For example, someone might say, “I’m feeling alt today” to show they’re going for a unique, edgy, or unconventional vibe.
2. Alternative account: Online, especially on social media like Instagram or Twitter, “alt” often refers to a secondary or backup account. You might see, “Follow my alt for memes”, meaning a fun or private account separate from their main profile.

So essentially, “alt” is about something different from the usual—whether it’s a style, a mood, or an account.
