pin (n.)youdaoicibaDictYouDict
late Old English pinn "peg, bolt," from Proto-Germanic *penn- "jutting point or peak" (cognates: Old Saxon pin "peg," Old Norse pinni "peg, tack," Middle Dutch pin "pin, peg," Old High German pfinn, German Pinne "pin, tack") from Latin pinna "a feather, plume;" in plural "a wing;" also "fin, scoop of a water wheel;" also "a pinnacle; a promontory, cape; battlement" (as in Luke iv:9 in Vulgate) and so applied to "points" of various sorts, from PIE *pet- (see pen (n.1)).

Latin pinna and penna "a feather, plume," in plural "a wing," are treated as identical in Watkins, etc., but regarded as separate (but confused) Latin words by Tucker and others, who derive pinna from PIE *spei- "sharp point" (see spike (n.1)) and see the "feather/wing" sense as secondary.
