Do you know ghouls from goblins and ghosts?
early 14c., "throw down or fall with force," perhaps from a Scandinavian source (cf. 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.
"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.
The sale of goods of one nation in the markets of a second nation at less than the price charged within the first nation. Dumping can eliminate competitors by undercutting their prices.
Harsh criticism; severe derogation: A coupon is provided on page 47 for your dumping (1950s+)
[origin uncertain; perhaps related to a Scandinavian term meaning ''to fall suddenly,'' the connection being the tipping out of a load from a cart]
