rater[1]

Etymology

It is from French rat + -er, made after the older phrase “prendre un rat”, said of a firearm that failed to go off.[2][3][4] That phrase is found as “prendre rat” in 1651 and as “prendre un rat” in 1668, when it also meant “to fail”; the verb replaced it, and it went out of use in the 19th century.[3] Rey reports Guiraud's explanation of the phrase: Old French raster “to scrape, gnaw” (see ratisser), the wheel of the musket and later the hammer of the gun scraping without striking a spark.[3] A verb rateler “to hunt rats” (1611), later found in a shorter form (1743–1752), has died out.[3]

Littré rejected the story that students made the verb from the canon-law formula “matrimonium ratum, sed non confirmatum”, since the word is too recent for so old a source.[5]

Earliest recorded meaning

Lesage uses it in Gil Blas (1715) for failing in an undertaking.[2] The Académie recorded it in 1718, both for a gun that does not fire and for not carrying a task through.[2][6]

Semantic evolution

From the start it meant both missing the game one aimed at because the shot did not go off, and failing at something;[2][3] Marivaux has the intransitive “to fail” in 1722.[2][3] Rater son coup is recorded in 1833, and in 1873 Flaubert uses it for failing to meet someone.[2] In the negative it became familiar: ne pas rater quelqu'un “to get even with someone” (1904) and ne pas en rater une “never to miss a chance to put one's foot in it” (1929).[2][3]

The past participle raté was used as a noun for a misfire of a gun (1836), then for a person who has failed in life (1867) and for the misfiring of an engine (1890).[3][2] Rey calls rater the familiar equivalent of manquer.[3]
