Hind means located at the back or rear of something. A dog's hind legs are its back legs, the ones it uses to push off when jumping or running. A horse rears up on its hind legs when it lifts its front hooves off the ground.

The word almost always appears right before the thing it describes: hind legs, hindquarters, hind feet. You wouldn't say “the legs that are hind,” you'd say “the hind legs.”

Think of how a kangaroo moves: its powerful hind legs do most of the work for those incredible jumps, while its smaller front legs barely touch the ground. Or picture a deer bounding through the forest: it pushes off with its hind legs to leap over fallen logs.

The opposite of hind is fore (meaning front), though people use “front” much more often in everyday speech. A ship has a fore and aft (front and back), but an animal has fore and hind legs. When you hear hind, you're almost certainly talking about an animal's back legs or rear section.
