Word Origin & History

stapes 
"stirrup bone in the middle ear," 1670, Mod.L. (1564), special use of M.L. stapes "stirrup," probably an alteration of L.L. stapia, related to stare "to stand" + pedem "foot." So called because the bone is shaped like a stirrup. This was an invented M.L. word for "stirrup," for which there was no classical L. word, as the ancients did not use stirrups.
