☀️ 日 sun + 爰 reaches out — sun reaches out, warmth
暖 decomposes as 日 (sun) + 爰 (to pull/reach). The sun extending its rays gives the sense of warmth. Pronounced nuǎn — rhymes with 'wan' said with a rising-falling tone.
暖 — sun radical 日 + 爰 (yuán, phonetic)
暖 is a semantic-phonetic compound. The 日 'sun' radical carries the meaning of warmth, while 爰 supplies the sound (historically close to 'nuǎn'). It originally described the warmth of sunlight and broadened to mean 'warm' in general — both physical heat and figurative warmth like kindness.
