preen

Etymology

From Middle English pren, from Old English prēon, from Proto-Germanic *preunaz (compare Icelandic prjónn (“pin, knitting-needle”), Danish pryne (“needle, eel-spear”)), of uncertain origin, but perhaps from Proto-Indo-European *brewn- (“protrusion, tip, edge”) (compare Lithuanian briaunà (“edge”), Albanian brez (“belt, girdle”)). Cognate with German Pfriem. The verb is from Middle English prenen, from pren (“a preen”), akin to German pfriemen.
