Stallion: A non-castrated male horse four years old and older. The term "horse" is sometimes used colloquially to refer specifically to a stallion. 

Gelding: A castrated male horse of any age. 

In horse racing, these definitions may differ: For example, in the British Isles, Thoroughbred horse racing defines colts and fillies as less than five years old.  However, Australian Thoroughbred racing defines colts and fillies as less than four years old.
