英文词源

challenge: challenge: [13] The original notion contained in challenge in English was of ‘accusation’. The word comes, via Old French chalenge or calenge, from Latin calumnia ‘false charge, deception’ (source of English calumny [15]). By the early 14th century, the modern, more neutral sense of ‘inviting to a contest’ had emerged, however, and before the end of the 17th century the word’s accusatory connotations had virtually died out.

Latin calumnia probably came from the verb calvī ‘deceive’. This may, via an unrecorded intermediary *calvilla, be related to Latin cavilla ‘raillery’, whose derived verb cavillārī was the source of English cavil [16].
=> calumny
challenge (n.): early 14c., "something one can be accused of, a fault, blemish;" mid-14c., "false accusation, malicious charge; accusation of wrong-doing," also "act of laying claim" (to something), from Anglo-French chalenge, Old French chalonge "calumny, slander; demand, opposition," in legal use, "accusation, claim, dispute," from Anglo-French chalengier, Old French chalongier "to accuse, to dispute" (see challenge (v.)). Accusatory connotations died out 17c. Meanings "an objection" in law, etc.; "a calling to fight" are from mid-15c. Meaning "difficult task" is from 1954.
challenge (v.): c. 1200, "to rebuke," from Old French chalongier "complain, protest; haggle, quibble," from Vulgar Latin calumniare "to accuse falsely," from Latin calumniari "to accuse falsely, misrepresent, slander," from calumnia "trickery" (see calumny).

From late 13c. as "to object to, take exception to;" c. 1300 as "to accuse," especially "to accuse falsely," also "to call to account;" late 14c. as "to call to fight." Also used in Middle English with sense "claim, take to oneself." Related: Challenged; challenging.
