A young horse is known as a foal. Horses come in many different breeds, including those classified as ponies. Ponies are small breeds of horses that, because of their size, appear much smaller when fully grown than larger breeds of horses.

To "pony up" in America is to pay some amount you owe, usually a large amount of money. Also, a "pony" could be a small amount of liquor or a small bottle of liquor. Also, a "pony" could be a cheat sheet or other material used in a test by students.

A pony is a small horse measuring less than 4 feet tall. While they look like mini versions of regular horses, ponies have a different temperament and sturdier builds than most full-size horses. Both horses and ponies are of the same species (Equus caballus) and come from the exact same family tree.
