Etymology

From Middle English pinne, from Old English pinn ("pin, peg, bolt"), itself from Proto-Germanic pinnaz, pinnō, pint- ("protruding point, peak, peg, pin, nail"). The Proto-Indo-European root is bend- ("protruding object, pointed peg, nail, edge").

The word has kept company with Germanic relatives: Dutch pin ("peg, pin"), Low German pin, pinne ("pin, point, nail, peg"), German Pinn, Pinne ("pin, tack, peg"), Bavarian Pfonzer, Pfunzer ("sharpened point"), Danish pind ("pin, pointed stick"), Norwegian pinn ("stick"), Swedish pinne ("peg, rod, stick"), Icelandic pinni ("pin"). The family resemblance is the protrusion itself — the quality of sticking out.

Latin pinna ("fin, flipper, wing-like appendage, wing, feather") is not in the bloodline, though confusion was common enough. Pinna extended to mean "ridge, peak, point" and gave English pinnacle; it was often mistaken for Latin penna ("wing, feather"). The resemblance is superficial. Pin and pen in their various English senses arrived by separate routes.
