What Is Leetspeak?
Leetspeak, or leet, is a way of writing that swaps letters for numbers and symbols that look like them. It started on early bulletin boards and online games. The name comes from "elite." People still use it for fun, for gamer tags and for inside jokes.
How to Read Leetspeak
Look at each number as the letter it looks like. Read the word out loud and your brain fills in the rest.

How to Write Leetspeak
Start light. Swap a, e, i and o in lowercase words, and leave names and short forms like DNS alone. That keeps it readable. When you want more, swap s, t, g, b and l too. Do not swap every letter, or nobody can read it, and that is no fun.
Tips for Newcomers
- Read slowly the first few times. It gets fast after a minute.
