||From Proto-Celtic *garrV- 'calf of the leg, shank' with cognates in Oir. gairr (i m or t) 'calf of the leg', MW garr m. 'leg, shank, ham, thigh', Co. gar 'leg' and Gaulish *garra > OFr. gare 'leg'. Matasović suggests to derive these forms from the PIE word for 'hand' (PIE *ghesr > Hitt. kissar, Gr. kheir, IEW 447) and gives two possible developments that would yield the Celtic forms regularly. The semantic development was then 'hand, arm'> 'limb'> '(calf of the) leg'.
