The kanji 懐 is a phono-semantic compound (形声文字, keisei moji). It combines the radical 忄 (りっしんべん, "heart" or "mind") with the phonetic component [笑] (懐), which conveys the sound and provides a semantic hint. The radical 忄 indicates that the meaning is related to emotions or feelings. The original form depicted a person holding something close to their chest or in their bosom, which then evolved to represent feelings of closeness, longing, and security.
