Slang in the World of Avatar

Slang refers to terms that are commonly used in everyday language but not considered official words, including exclamations and non-traditional insults. There are several types of slang in the World of Avatar, particularly in the Fire Nation. As with all languages, slang changes over the course of time.

Terms
