mousse

Etymology

It is borrowed from French mousse (“froth; moss”).^{[2][3][4][5][6][7]} Its further origin is disputed.^[2][6] Barnhart, Etymonline, Merriam-Webster Unabridged and Klein trace the French word to Old French mousse (“froth, scum”),^[3][4] from Late Latin mulsa (“mead, hydromel”),^[3][4][5][8] from Latin mulsum (“honey wine, mead”), the neuter of mulsus (“mixed with honey”), related to mel (“honey”),^[3][4] from Proto-Indo-European *melit- (“honey”).^[3][6] The OED instead takes the foam sense, recorded in French from 1680, as a special use of the French word for moss, the same word as English moss,^[2] and Hoad, Ayto and the Oxford Dictionary of Word Origins likewise connect it with moss;^[7][9][10] Ayto has French borrow it from Middle Low German mos (“moss”).^[9] The American Heritage Dictionary takes the French word as partly Germanic and partly Latin.^[6] The dish of whipped cream is recorded in French from 1755.^[2]

Earliest recorded meaning

Etymonline finds it in 1769 as a French word in English cookery, for a frothy dish of whipped cream and sometimes egg.^[3] The OED's first record is of the froth on sparkling wine, in T. G. Shaw's Wine (1863),^[2][11] and Etymonline dates that use to 1840, after French vin mousseux.^[3]

Semantic evolution

The froth on champagne came first in the OED's record, and the dish followed: the OED's first quotation for a sweet or savoury dish lightened with whipped cream, gelatin or egg white is from an American newspaper of 1885,^[2] the date Merriam-Webster Unabridged also gives,^[5] while Barnhart has 1892.^[4] The Oxford Dictionary of Word Origins likewise puts the food sense some twenty years after the wine sense.^[10] In the late 20th century the word was extended to things with a similar texture: a brown emulsion of sea water and oil from weathered oil spills (1968), a foamy skin cream (1971) and a foam for setting or styling the hair (1982 in the OED,^[2] 1977 in Etymonline,^[3] the 1970s in Barnhart^[4]). The Oxford Dictionary of New Words links the spread of hair mousse to the fashion for blow-dried hairstyles in the late 1970s and to a French firm's marketing of the product under the French name in the early 1980s, so that this sense may be a fresh borrowing from French.^[12] The verb, to apply mousse to the hair, followed in 1984.^[2][3]
