Eleet or leetspeak, is an alternative alphabet for many languages that is used primarily on the Internet. It uses some characters to replace others in ways that play on the similarity of their glyphs via reflection or other resemblance. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t.
