About

The character "代" is composed of the person radical "亻" and the component "弋", which historically served as a phonetic element. Its etymology centers on the idea of substitution, originally representing one person taking the place of another, hence the core meaning "to replace" or "act on behalf of". From this foundational sense, the character's meaning broadened to denote sequential periods, such as "generation" or "dynasty", conceptualized as one age succeeding another. Further semantic extension led to its use in referring to historical eras, geological epochs, and administrative roles, consistently building upon the inherent notion of succession and replacement.
