Verlan

Verlan is an argot in the French language, featuring inversion of syllables in a word, and is common in slang and youth language. It rests on a long French tradition of transposing syllables of individual words to create slang words. The name verlan is an example: it is derived from inverting the syllables in l'envers ("the inverse," pronounced lan-ver).
