Summary: The Latin root word *ped* and its Greek counterpart *pod* both mean "foot." These roots are the word origin of many English vocabulary words, including [*ped*]al centi[*ped*]e, [*pod*]ium, and [*pod*]iatrist. Humans, for instance, are bi[*ped*]al because they walk on two "feet," whereas a tri[*pod*] is a stand for a camera that has three "feet."
