Word Origin & History

damp
early 14c., probably in O.E., but no record of it. If not, probably from M.L.G. damp; ult. from P.Gmc. *dampaz. Originally "a noxious vapor;" sense of "moisture" is first attested 1706. Damper of a piano is from 1783; of a chimney, 1788; either or both of which led to various figurative senses.
