scorn: [12] Scorn reached English via Old French, but it is ultimately of Germanic origin. Its immediate source was Old French escharnir, a descendant of Vulgar Latin *escarnīre. This had been borrowed from a prehistoric Germanic *skarnjan ‘mock, deride, make fun of’. A product of the same base was Middle High German scherz ‘joke, jest’, which was borrowed into Italian as scherzo and subsequently made its way into English as the musical term scherzo ‘lively passage’ [19].

scorn (n.)youdaoicibaDictYouDict
c. 1200, a shortening of Old French escarn "mockery, derision, contempt," a common Romanic word (Spanish escarnio, Italian scherno) of Germanic origin, from Proto-Germanic *skarnjan "mock, deride" (cognates: Old High German skern "mockery, jest, sport," Middle High German scherzen "to jump with joy").

Probably influenced by Old French escorne "affront, disgrace," which is a back-formation from escorner, literally "to break off (someone's) horns," from Vulgar Latin *excornare (source of Italian scornare "treat with contempt"), from Latin ex- "without" (see ex-) + cornu "horn" (see horn (n.)).
