Etymology

Origin of dump

First recorded in 1300–50; Middle English dompen, dumpen in the sense “to fall suddenly, plunge,” from Old Norse dumpa “to thump, strike, bump”; modern senses of the transitive verb and noun are unknown before the 19th century, perhaps derive from another source, or are an independent expressive formation
