The kanji 替 primarily conveys the idea of "to replace," "to substitute," "to exchange," or "to change." It implies a swapping of one thing for another, often with the intention of replacing something old or worn out with something new, or of trading one thing for something of equivalent value. It also includes the meaning of an acting role or function to someone instead of someone else.

The kanji 替 is a phono-semantic compound (形声文字). It combines the phonetic component 㚘 (tai, meaning "rule" or "to be regulated") with the semantic component 日 (hi, meaning "sun" or "day"). The phonetic component suggests the sound, while the semantic component hints at a time-related aspect, as in the change of the day when a replacement occurs. Over time, the form evolved to the current shape, with the meaning consistently revolving around the ideas of substituting or exchanging.
