Forms
gâcher[1] Old French gaschier (1260), Middle French gascher (15th century); the spelling with ⟨â⟩ dates from the 17th century.[2][3]
Etymology
It is inherited from Old French gaschier, borrowed from Frankish *waskōn (“to wash, to soak”),[3][2][4][5] reconstructed from Old High German wascan and Middle Dutch wasschen,[3][2] and related to German waschen and English wash;[2][6] Wiktionary traces it to Proto-Germanic *waskaną.[1] The TLFi thinks the Frankish verb entered Gallo-Romance in the general sense “to put through water, to wash roughly”, which survives in northern dialects for the first rinsing of linen, and is the source of the technical and the pejorative senses.[3] Bloch and Wartburg give the Frankish form as *waskan.[7]
Pierre Guiraud proposed instead Vulgar Latin *vasicō (“to stir like grapes in the vat”), a Gallo-Romance form, from Latin vās (“vessel”).[2][6] Littré related the verb to Italian guazzare (“to soak”).[8]
Earliest recorded meaning
Étienne Boileau's Livre des métiers (1260) has gaschier for soaking fish in water to remove the salt;[3][2] an ordinance forbids the fishmongers of Paris to gascher salt cod, mackerel or herring.[8]
Semantic evolution
From “to stir in water, to wash roughly”, the verb came to mean mixing mortar or plaster with water (early 14th century, though the 1314 record in Fauvel is uncertain; securely about 1450).[3][2][7] A regional, rural sense is “to knead”,[2] and in 1538 Estienne records it for “to row”, an oar being a gâche that stirs the water.[3][2]
From the idea of quick, rough work the figurative senses followed: “to sell one's goods too cheap, to work for too little” (Savary, 1741), “to do a job badly” (d'Hautel, 1808) and “to waste, to spoil” (Larousse, 1872), now the commonest use.[3][2][4] Gâcher le plaisir of someone dates from the early 20th century.[4] The derivative gâchis followed the same path, from “mortar” to “a mess” (1775).[2][7]
