演变
yǎnbiàn · HSK 7
to develop; to evolve
🦋 演 develop + 变 change = something develops and changes, i.e. evolves over time
演变 yǎnbiàn pairs 演 (develop, unfold) with 变 (change). Together they name a slow, step-by-step change of form, the way a caterpillar turns into a butterfly through many stages.
演 — water 氵 + 寅 (yín, phonetic)
演 is a semantic-phonetic compound: the water radical 氵 gives the meaning, originally referring to water flowing far and spreading out, while 寅 supplies the sound. From 'water extending' it broadened to 'develop, elaborate, perform,' as in unfolding a story or acting out a play.
变 — top 䜌 (phonetic) + bottom 又 (hand)
Originally written 變, a phonosemantic compound: 䜌 (luán) gives the sound while 攵 (a hand with a stick) suggested the action of changing or transforming. The simplified form 变 keeps the phonetic top in reduced shape over 又 (hand). Core meaning: to change, transform, or alter.
