Origin

The character combines a person radical on the left with a sound hint on the right that suggests the pronunciation. The core meaning comes from the idea of one person taking the place of another—hence substitute or replace. Over time, this sense of "taking someone's place" extended to mean a period of time when someone holds power (an age or era), and then more generally to any kind of change or conversion. The person radical makes clear the concept centers on human substitution or succession.
