Leetspeak, also known as eleet or leet, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance. Additionally, it modifies certain words based on a system of suffixes and alternate meanings. Leetspeak is a way of writing words by replacing some letters with numbers or symbols that look similar to them. For example, the word “leet” can be written as “1337” or “l33t”.

Leetspeak is an internet phenomenon that predates the World Wide Web. It’s a style of typing that replaces English letters with similar-looking numbers or symbols, and its closely tied to early hacking and gaming culture. Leetspeak was originally used by computer programmers and hackers to avoid text filters and show their skills. Later, it became popular among online gamers and internet users who wanted to have fun or mock newcomers. Leetspeak has many variations and can be hard to read for people who are not familiar with it.
