Kids Definition

quarter horse

noun

: any of a breed of stocky muscular horses capable of high speed for short distances

Word Origin

Quarter horse might seem like a strange name for an animal that is not only full-sized but quite sturdy and muscular. However, the breed gets its name not because it is a fraction of a horse but because it can run very fast for short distances. Unlike the slender, long-legged Thoroughbred horse, the compact quarter horse is built for quick bursts of speed. For about a quarter-mile the quarter horse probably can run faster than any other breed of horse. After that distance the quarter horse begins to slow down and can be beaten in a race with other horses.
