Leetspeak (or "1337") is an alternative alphabet used primarily on the internet. It replaces letters with numbers or special characters that resemble the letters. For example:

  • A → 4, /-\, @
  • B → 8, |3, 13
  • E → 3, &, €
  • S → 5, $, §

Leetspeak originated in the 1980s among hackers and gamers as a way to bypass text filters or simply look cool. Today it's used for fun, memes, and playful communication online.
