- pin: [OE] Latin pinna (a probable relative of English fin) meant ‘wing, feather, pointed peak’. Amongst its derivatives were the diminutive pinnāculum, which has given English pinnacle  and, via French, panache  (which originally meant ‘plume of feathers’), pinnātus ‘feathered, winged’, source of English pinnate , and Vulgar Latin *pinniō, from which English gets pinion ‘wing’ . Pinna itself was borrowed into Old English as pinn, and it was used for ‘peg’ (a sense which survives in various technical contexts); the application to a ‘small thin metal fastener’ did not emerge until the 14th century.
A pinafore  is etymologically a garment that is ‘pinned afore’, that is, ‘pinned to the front of a dress to protect it’.
=> fin, panache, pinafore, pinion, pinnacle
- pin (n.)
- 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.
