Tutor's tip: A "biped" is a two-footed animal, while a "bipod" is a two-legged stand.
Bipedalism is standing, or moving for example by walking, running, or hopping, on two appendages (typically legs). An animal or machine that usually moves in a bipedal manner is known as a biped (/'baɪ.pɛd/), meaning "two feet" (Latin bi = two + ped = foot).
