From Middle English cunte, queynt, queynte, from Old English cunte, from Proto-West Germanic kuntā, from Proto-Germanic *kuntǭ. Cognate with West Frisian kunte, Middle Dutch conte (Dutch kont (“butt”)), dialectal Swedish kunta, dialectal Danish kunte, and Icelandic kunta. A relationship to Latin cunnus has not been conclusively shown. Lexicographer Partridge suggests cuneus (“a wedge”).
