dump: [14] Dump is probably of Scandinavian origin – Danish and Norwegian have the similar dumpe and dumpa, which mean ‘fall suddenly’ – although Dutch dompen ‘immerse, topple’ is another candidate that has been put forward. Either way, there does not seem to be any direct connection with the dumps [16], which was probably originally a metaphorical use of Dutch domp ‘haze’, in the sense ‘miasma of depression’. Nor has any relationship been established with the obsolete noun dump ‘lump’ [18], which appears to have close ties with dumpling [16] and dumpy [16], although whether as source or descendant (by backformation) is a debatable point.
dump (v.)
early 14c., "throw down or fall with force," perhaps from a Scandinavian source (compare Danish dumpe, Norwegian dumpa "to fall suddenly"). The sense of "unload en masse" is first recorded in American English 1784. That of "discard, abandon" is from 1919. Related: Dumped; dumping. Dump truck is from 1930.
dump (n.)
"place where refuse is dumped," 1865, originally of mining operations, from dump (v.). Meaning "any shabby place" is from 1899. Meaning "act of defecating" is from 1942.
