dampen

Etymology

It is formed from English damp + -en, the suffix that makes verbs from adjectives,^{[2][3][4][5][6]} or is a derivative form of the verb of the same spelling.^[2][4] The adjective comes from the noun, first recorded in the early 14th century for a stifling, poisonous vapour in a coal mine; the noun is perhaps an unrecorded Old English word, but more probably from Middle Low German damp, and in either case goes back to Proto-Germanic *dampaz,^[3] the source also of Old High German damph, German Dampf (“vapour, steam”) and Old Norse dampi (“dust”).^[3][2] The Middle English Dictionary records a verb dampen, to stifle or suffocate, from the noun, in “Cleanness” (about 1400);^[7] the OED takes this as the verb damp, and assigns the form in “Cleanness” to dump.^[2]

Earliest recorded meaning

To check the vigour of something; to dull, deaden or depress: Merriam-Webster Unabridged dates this sense to 1547,^[5] and the Shorter Oxford also to the mid-16th century.^[4] The OED's first quotation is from Phineas Fletcher's The Purple Island (1633),^[2] and Etymonline dates it to the 1630s,^[3] Dictionary.com to 1620–30.^[6]

Semantic evolution

Like the older verb damp, which had passed from suffocating with foul air to checking the force of the spirits by the 1540s,^[3] dampen was at first used figuratively, of spirits, ardour and force.^[2][3] From 1686 it was also intransitive, to become dull or damp.^[2][4] The literal sense, to make damp or moisten, appears only in 1827, in James Fenimore Cooper's Red Rover,^[2][3] and in 1879 the word was used in magnetism, as damp already was, of checking oscillations.^[2][4] The Century Dictionary noted in 1897 that dampen had become the more common word in the literal sense, and was only sometimes used in the derived ones.^[3]
