The kanji 退 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is a component representing movement or walking (usually derived from 彳/行). The right side is 㞐, which functions as the phonetic component, conveying the sound "tai". Together, they visually suggest the action of going backwards or retreating. The character's evolution shows a simplification of the original form, but the core meaning of withdrawal and retreat has remained consistent throughout its history.
