Forms
asseoir[1] Old French asseir (about 980), asseoir; the 1990 spelling reform allows assoir.[2][1] Both present tenses j'assieds and j'assois are in use, Littré traced them to western and central pronunciations.[2][1][3][4]
Etymology
It is inherited from Old French asseoir, inherited from Vulgar Latin *assedeō, a remaking after the simple verb sedeō (“to sit”) of Latin assideō (“to sit beside”), from ad (“to”).[5][6][4][7][1] Latin “assidēre” also meant “to tend (a patient)” and “to besiege”, a sense frequent in Old French.[6][3]
South of a line from the Gironde estuary to northern Lorraine, dialects use descendants of a derived “*assedītāre”, like Old Occitan assetar and Italian assettare.[6] The reflexive s'asseoir“ replaced ”se seoir, still used in the early 18th century.[6]
Earliest recorded meaning
About 980 the Passion of Clermont uses asseir for “to place, fix”.[2][5] The reflexive is found in the mid-11th century, and the Chanson de Roland has Al faldestoed s'est Marsiles assis “Marsile sat on the throne”.[5][3]
Semantic evolution
From 1119 it also meant “to establish, institute”, and, from the 12th century it was said of fixing a tax or rent, in connection with assiette.[5][8] The transitive asseoir quelqu'un “to seat someone” is found in the 13th century.[5] Asseoir un camp, asseoir son autorité continue the sense “to set firmly”.[3][8]
In 19th-century familiar speech asseoir meant “to dumbfound” (Zola, 1875), and va t'asseoir ! was a popular retort (1869).[9] The participle assis gives magistrature assise and the vote par assis et levé.[5]
