Man with a body like a horse? (7)
I believe the answer is:
centaur
(Other definitions for centaur that I've seen before include "Mythical horseman!" , "Mythical semi-equine beast" , "Mythical creature with horse's body and man's upper torso" , "Mythical creature with the head of a man and the body of a horse" , "Mythological man-horse" .)
