Chinese Language --- Jia Jie

Jia Ji refers to a character that is borrowed to represent an unrelated word because of its phonetic similarity to that word.

For example, the character bei is a representation of two people standing back to back, and first meant "back." However, this character was later borrowed (Jiajie) to represent the sound bei, meaning "north." To resolve the confusion resulting from one character being used to represent two different words, a component meaning "flesh" yue was added underneath the bei character, resulting in the character bei, to represent the original meaning of "back."
