γωνία

From a derivative of γόνυ (gónu, “knee”), ultimately from Proto-Indo-European *ǵónu (“id”). The long ω (ō) is from the regular Doric development of an unattested *γονϝ-ία (*gonw-ía), as the paradigm of *ǵónu shows no lengthened grade (thus precluding a derivation from such an ablaut), while most mathematicians in Greek antiquity (who were most likely responsible for the word's formation) were Pythagorean (and thus wrote in Doric).^[1]
