The word tripod is probably derived from Greek: from tri for "three" and podos for "foot." Thus the word tripod means literally three footed.Tripods have only three legs because even on an uneven surface something having only three legs will still not wobble, as something with four legs would. Most camera tripods have legs which are adjustable in length to make a strong, level camera platform.
