Is there a general word or phrase that denotes an animal providing the motive power for a vehicle?
Something that might conceptually complete the phrase: "cars have engines; chariots have _______."
(I don't mind if the word semantically refers to horses, but ideally I would rather one that doesn't contain the string "horse".)
Some words or phrases that are similar to what I'm looking for, but don't quite fit:
- "Steed" or "Mount" - except that such an animal is being ridden, not moving a vehicle.
- "Beast of burden" - except that the emphasis is placed upon carrying a load, not moving a vehicle.
- "Workhorse" - except that the meaning is much, much broader than moving a vehicle; and it also contains the string "horse", which I would ideally avoid.
