驾驭
jià yù · HSK 7
to drive
🐎 驭 = 马 horse + 又 hand: a hand on the reins steers the horse
Both characters carry 马 (horse). 驾驭 literally means handling a horse, which broadened to steering, driving, or mastering anything you control.
驾 — 加 (jiā, phonetic) + 馬 horse
A semantic-phonetic compound: 馬 'horse' gives the meaning (yoking horses to a vehicle), while 加 supplies the sound. Originally meant to harness horses to a chariot, then broadened to 'drive' a vehicle and, by extension, to pilot or operate.
