The kanji 還 is a phono-semantic compound (形声文字). The phonetic part is 爰（えん, en）, which contributes the sound, and the semantic part is 辶（しんにょう, shinnyou, "road" or "movement"), which indicates the meaning of movement. This combination suggests a movement that comes back or returns along a path or road. The original form of the character shows a person being led back, further reinforcing the idea of returning or going back.
