bump (v.)[bump 词源字典]: 1560s, "to bulge out;" 1610s, "to strike heavily," perhaps from Scandinavian, probably echoic, original sense was "hitting" then of "swelling from being hit." Also has a long association with obsolete bum "to make a booming noise," which perhaps influenced surviving senses such as bumper crop, for something full to the brim (see bumper). To bump into "meet" is from 1880s; to bump off "kill" is 1908 in underworld slang. Related: Bumped; bumping. Bumpsy (adj.) was old slang for "drunk" (1610s).[bump etymology, bump origin, 英语词源]
hurt (v.): c. 1200, "to injure, wound" (the body, feelings, reputation, etc.), also "to stumble (into), bump into; charge against, rush, crash into; knock (things) together," from Old French hurter "to ram, strike, collide," perhaps from Frankish *hurt "ram" (cognates: Middle High German hurten "run at, collide," Old Norse hrutr "ram"). The English usage is as old as the French, and perhaps there was a native Old English *hyrtan, but it has not been recorded. Meaning "to be a source of pain" (of a body part) is from 1850. To hurt (one's) feelings attested by 1779. Sense of "knock" died out 17c., but compare hurtle. Other Germanic languages tend to use their form of English scathe in this sense (Danish skade, Swedish skada, German schaden, Dutch schaden).
dunt: "Bump into or hit heavily", Late Middle English: perhaps a variant of dint.
