What Is Leet Speak?

Leet speak, also written as 1337 or l33t, is a substitution cipher where letters are replaced with numbers and symbols that look similar. A becomes 4, E becomes 3, T becomes 7, and so on. The name comes from the word "elite," which in leet speak is written as 3l173.

It started in the 1980s on early bulletin board systems where skilled hackers and programmers used it to identify themselves as part of an in-group. By the 1990s it spread into gaming communities and online forums, becoming one of the first true internet languages. Leet speak names were everywhere in early multiplayer games, usernames packed with numbers and symbols that looked impossible to read at first glance.

I remember seeing a username like "H4x0r" as a kid and having no idea what it said. Once someone explained the pattern it clicked immediately, and I started spotting it everywhere online.
