What is leet speak?
Leet (from 'elite') is an informal writing system that substitutes numbers and symbols for letters — A becomes 4, E becomes 3, and so on. It originated in early online communities and BBS boards in the 1980s as a way to slip past keyword filters, then became a marker of internet identity through the 1990s gaming scene.

Frequently Asked Questions
Is leet speak still used?
Mostly ironically. It's a recognizable shorthand for old-school hacker or gamer identity, and it still appears in usernames, memes, and nostalgia content.
Why doesn't every letter get substituted?
Some letters don't have a widely recognized leet equivalent. Those pass through unchanged so the result stays readable.
