frown

Origin

From Middle English frounen (“to frown as an expression of disapproval, displeasure, shame, fear, or jealousy”), from Old French froignier, froingnier, frognier (“to wrinkle the mouth or forehead, frown, scowl”), of uncertain and disputed origin. Perhaps from Medieval Latin fruncāre (“to wrinkle, crease, turn up one's nose, make a face, frown”) (compare Old High German fruncetura (“wrinkle”), via Latin), from Frankish *hrunkwittjā (“wrinkle”)/*hrunkwōn (“to wrinkle”), whence Old High German runza (“wrinkle”). See also French froncer (“to frown, scowl”). Alternatively, perhaps from Gaulish *frognā (“nostril”), from Proto-Celtic *srognā (“nose”). Still yet, perhaps of North Germanic origin, related to Swedish fryna (“to frown, frown with one's nose, make a wry face”), Norwegian frøyna (“to wrinkle up one's nose, make a wry face; snort”). Compare also dialectal English frine (“to frown, whine, complain”).
