骑车
qí chē · HSK 2
to cycle
🚴 骑车 = ride + vehicle
骑 means to ride (originally astride a horse, with the 马 horse radical) and 车 means vehicle or cart. Together they mean to ride a bike or cycle.
骑 — horse radical 马 + 奇 (phonetic)
A semantic-phonetic compound. The horse radical 马 gives the meaning 'to ride (a horse)', while 奇 (qí) supplies the sound. Originally specific to riding horses, the meaning later broadened to riding bicycles, motorcycles, and other straddled vehicles.
车 — pictograph of a chariot/cart
车 is a pictograph originally drawn as a top-down view of a chariot, showing the axle, wheels, and carriage box. The ancient form 車 clearly depicted two wheels connected by an axle. It still means vehicle, cart, or car today.
