Forms
savoir[1] Old French savir (842, as a noun), saveir (about 980), savoir (about 1165).[2][3] From the 15th to the 17th century it was also written sçavoir, as if from Latin scīre.[2][4]
Etymology
It is inherited from Old French saveir, inherited from Vulgar Latin *sapēre, an alteration of Classical Latin sapere (“to taste; to be wise; to understand”).[2][5][3][6] The Latin verb meant “to have a taste, a smell” and “to perceive by taste”, hence figuratively “to have sense, to be wise”, and as a transitive verb “to understand”, already in the Republican period, and “to know” in Late Latin.[2][6] Supported by sapiēns, it eliminated scīre (“to know”), which survives only in Romanian ști and Logudorese “iskire”.[6] The present “sais” comes from Vulgar Latin “*sayo”, and the subjunctive “sache” from sapiat, with the regular change of [pj].[1]
The Latin verb has a Germanic correspondent in Old Saxon afsebbian (“to perceive”).[2] Cognate with Italian sapere, Occitan saber, Catalan saber, Spanish saber and Portuguese saber.[7][4]
Earliest recorded meaning
The infinitive is first found in the Strasbourg Oaths (842), used as a noun: in quant Deus savir et podir me dunat “as far as God gives me knowledge and power”.[8][9] As a verb it appears at the end of the 10th century, with an infinitive, “to be able to”: de Crist non sabent mot parlar “they could not say a word about Christ”.[8]
Semantic evolution
In the second half of the 10th century savoir + clause meant “to know something from having been told”, and about 1100 “to be able to do something” by talent or practice (Ben set parler “he can speak well”).[8][2] About 1050 it was a weakened equivalent of pouvoir (Ne vus sai dire “I cannot tell you”), a use that survives in the negative conditional (je ne saurais) and in Belgian French in the positive.[8][1] The imperative sachez calls for attention from about 1100, and que je sache “as far as I know” is found in 1176–81.[8]
The noun savoir meant “wisdom, intelligence” in the oldest texts and “knowledge acquired by study” from about 1155.[9][3] Derivatives include savant (12th century, a noun from 1634), savoir-vivre (1466) and savoir-faire (1671).[6]
