soft
🧶 柔 soft + 软 soft = doubly soft; both halves mean soft, like a pliant yarn
软 carries the 车 (vehicle) radical beside 欠 — a cart that yields and flexes rather than staying rigid. Pairing 柔 with 软 stacks two soft words, so 柔软 means supple, bendy, whippy.
软 — car radical 车 + 欠 (yawn/lack)
Originally written 輭 or 軟, combining 車 (cart) with a phonetic element. The cart component suggested the flexible, yielding leather or padding used in carriages, giving rise to the meaning 'soft' or 'pliant.' The modern simplified form 软 keeps 车 with 欠 as the phonetic.
