Related: Scorned; scorning.
OED rejects the suggestion that the vowel change in the Romanic languages might be by influence of or confusion with Old French escorner "deprive of horns," hence "deprive of honor or ornament, disgrace," from Vulgar Latin *excornare (source of Italian scornare "treat with contempt"), from Latin ex- "without" (see ex-) + cornu "horn" (see horn (n.)).
