Forms

ainsi[1] Old French ensi (mid-11th century), einsi (1080), issi, ainsi from the 13th–14th century.[2][3][4][5]

Etymology

It continues Old French ensi, einsi, of complex origin.[6][4] The second element is “si”, from Latin sīc (“thus”); the first is uncertain.[6][3][7][8] Bloch and Wartburg, followed by the GLLF, explain “einsi” as a crossing of eastern “ensi” (from “en” and “si”) with western and Norman “eissi”, borrowed from Old Occitan aissi, from a popular Latin “*accum sīc”, with “accum” a variant of ecce (“behold”).[4][5][6]

Wiktionary suggests Latin “ad” + “in” + “sīc”, Pierre Guiraud saw the influence of Old French ains “but, rather”, giving the sense “in this way rather than another”.[1][6][3] Diez proposed Latin “aequē sīc”, which Littré rejected in favour of “in sīc”.[9] Compare Italian così, Spanish así, Catalan així and Portuguese assim.[1][4]

Earliest recorded meaning

In the mid-11th century the Vie de saint Alexis has Iluec converset ensi dis e set anz “he lived there thus for seventeen years”, in the sense “in this way”.[2][6]

Semantic evolution

From the first texts it was an adverb of manner, “in this way”.[6] From 1539 it introduced a wish with the subjunctive: ainsi soit-il, the formula ending prayers, which renders amen.[2][6][5] The conjunction ainsi que meant “just as” (about 1200) and “at the moment when” (1330); the temporal sense died out in the 17th century.[6]

It also marks a conclusion (ainsi donc) and, in literary style, introduces the second term of a comparison (comme… ainsi).[5][10] Phrases include pour ainsi dire, et ainsi de suite and s'il en est ainsi.[5][7]
