Forms

septembre m (plural septembres)[1] Old French september (about 1119) beside the inherited setembre (about 1155) and sietembre;[2][3][4] septembre from 1226.[2][3][4] Anglo-Norman also has settenbre and setumbre.[5]

Etymology

It is borrowed from Latin september, first recorded in the computus of Philippe de Thaon (1119).[6][7][2] The Latin name is a derivative of septem (“seven”) (see sept): it was the seventh month of the old Roman year, which began in March.[6][2][8]

Old French also had the inherited form setembre (about 1155), in use until the 14th century; the modern spelling (1226) is a remaking of it after the Latin.[2][9][10] Bloch and Wartburg note that the old pronunciation without /p/ is rare in the northern dialects, though it survives at Pontoise in the name of a local fête.[10]

Cognate with Italian settembre, Spanish setiembre and Portuguese setembro.[4][10]

Earliest recorded meaning

Philippe de Thaon's Comput (1119) has it as the ninth month of the year;[6] Wace writes setembre about 1155.[3]

Semantic evolution

The word has always named the ninth month of the year.[6][2] Massacres de Septembre names the revolutionary killings of 2–5 September 1792, a phrase found in Chateaubriand's Mémoires d'outre-tombe and probably used much earlier;[2][3] from it came septembriseur (1792) and septembriser (1793) “to execute summarily and in a mass”.[2]

Purée septembrale (1534, Rabelais) is a joking name for wine, since grapes are picked in this month.[10][4]
