gâteux (feminine gâteuse, masculine plural gâteux, feminine plural gâteuses)[1]
Etymology
It is formed from French gâter + -eux, the verb being used in its medical sense “to soil oneself, pass urine and stools without control”.[2][3] The suffix is here a dialect form of -eur, used in mockery; the word began as a pejorative variant of gâteur, one who soils his sheets and clothes, in hospital slang.[2][4][5][6] Old French gaster already meant “to waste, spill (a liquid)”, and soi gaster “to soil oneself”, in the 12th century.[2][6]
The verb is from Latin vastō (“to lay waste”), its initial changed to /w/ under the influence of a Germanic stem.[4]
Earliest recorded meaning
It is first recorded as a noun in the supplement to the Académie's dictionary of 1836, for an invalid who cannot control his bladder or bowels and so soils his bedding;[2][3] Bloch and Wartburg date it to Balzac in the same year.[4] The Grand Robert, the Petit Robert and Rey give 1835, in hospital slang.[5][7][6]
Semantic evolution
By extension, from the middle of the 19th century, gâteux described a person, usually old, whose mental faculties were failing,[6][3] and by exaggeration, from 1872, it came to mean simply “idiotic”.[6][7] A further sense, someone made foolish by a strong feeling such as doting love, is dated to Courteline in 1893 by the GLLF.[3] The noun use for “a person without intelligence” is found in Zola in 1886.[8]
It gave gâtisme (1868) and gâtifier (about 1950, after bêtifier).[6]
