pie
/ˈpje/ · A1 · noun · m
foot
🦶 pie = Latin pes, pedis: same root as pedal, pedestrian, pedicure
Latin pedem lost its d and the e broke into ie, giving pie. English kept the d in pedal and pedestrian, all foot words. It is also a unit of length, just as English measures in feet. Said as one syllable: pyeh.
