Origin of stapes
noun plural stapes or stapedes (stæˈpiːdiːz)
Word Origin for stapes
"stirrup bone in the middle ear," 1660s, from Modern Latin (1560s), special use of Medieval Latin stapes "stirrup," probably an alteration of Late Latin stapia, related to stare "to stand" + pedem, accusative of pes "foot" (see foot). So called because the bone is shaped like a stirrup. This was an invented Medieval Latin word for "stirrup," for which there was no classical Latin word, as the ancients did not use stirrups.
