变动
biàndòng · HSK 5
change
🔀 变 = change + 动 = move; together: a moving change, i.e. fluctuation
变 carries the sense of transformation or alteration, while 动 means to move or act. Combined, 变动 names a shift that is actively happening — a change in motion, hence change or fluctuate.
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.
动 — force 力 + heavy/重 (simplified from 動)
The traditional form 動 combines 重 (heavy) as the phonetic with 力 (force/strength) as the semantic, suggesting the effort needed to move something heavy. The simplified form 动 replaces 重 with 云, keeping 力 to convey action and motion.
