‘堕马’ literally means 'to fall from a horse' — the character 堕 (duò) means 'to fall' or 'to drop', often with a sense of suddenness or loss of control, while 马 (mǎ) means 'horse'. Together, they form a classical and literary compound describing the physical act of falling off a horse, typically during riding. It is not used for general 'falling' — only specifically from horseback.

This term appears most often in historical texts, martial arts literature, or formal descriptions of equestrian accidents. Though still understood today, it is rarely used in casual modern speech; native speakers would more commonly say ‘从马上摔下来’ (cóng mǎ shàng shuāi xiàlái) in everyday contexts. The word carries a slightly archaic or dramatic tone, evoking imagery of ancient cavalry, jousting, or traditional Chinese horsemanship.
