A leg is something used to support things; to hold them up. Birds and humans have two legs. Some objects, for example tables and chairs, also have legs to hold them up.

Animals normally have 2 or 4 legs (vertebrates, which are animals with a backbone), or 6, 8, or 12 (arthropods, for example insects and spiders). Centipedes and millipedes have a lot more legs, but not exactly a hundred or a thousand as their names make people who do not know them think.

Biped is an animal with two legs and quadruped is an animal with four legs.

People also use the word "leg" in idioms, for example: you don't have a leg to stand on (that means "you have no support; you have no chance in this discussion") or to leg it (to run).
