🔄 变 = change + 更 = renew/alter; both halves mean 'change'
变 (biàn) means change/transform and 更 (gēng) means to renew or alter. Stacking two change-words intensifies the meaning into a formal 'modification' or 'alteration', common in official or written contexts.
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.
更 — 丙 (bǐng) phonetic + 攴/攵 (action/strike)
Originally an oracle-bone graph showing a hand striking a watch-drum to mark night watches, hence 'to change shifts.' From this came the meanings 'to change' and 'to replace' (gēng). The reading gèng later developed the sense 'further, even more,' as in 'one watch further on.'
