Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English bonet, cap, from Old French, material for a headdress, perhaps from Medieval Latin obbonis, probably of Germanic origin.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Middle English bonet, from Middle French bonet (Modern French bonnet), from Old French bonet ("material from which hats are made"), from Frankish *bunni ("that which is bound"), from Proto-Germanic *bundijan (“bundle”), from Proto-Indo-European *bʰendʰ- (“to tie”). Compare also Late Latin abbonis, obbonis ("ribbon of a headdress"), also of Germanic origin, from Frankish *obbunni, from *ob- ("above, over") + *bunni. Cognate with Old High German gibunt ("band, ribbon"), Middle Dutch bont ("bundle, truss"), Gothic 𐌲𐌰𐌱𐌿𐌽𐌳𐌹 (gabundi, "bond"). More at over, bundle.
