Etymology

It is inherited from Old French us, inherited from Latin ūsus (“use, practice, experience”).[1][2][3][4] Rey treats it as a borrowing of the Latin word.[5] The Latin noun is the action noun of ūtor (“to use”), which also gave user.[5][6] Cognate with Romanian uz, Italian uso, Spanish uso, Portuguese uso, Occitan us and Catalan ús.[6][7]

Earliest recorded meaning

Wace has aveir en us + infinitive, “to be used to doing something”, about 1150, and in 1155 turner en costume e en us “to make a habit of”.[2][5] Wace also has custume et us about 1155, and Garnier de Pont-Sainte-Maxence us et custume about 1190.[8]

Semantic evolution

In Old French the word had the main senses of the Latin: “habit”, as in estre a us “to be in the habit”, current until the 18th century, and “use, employment” (about 1175), which became archaic.[5][2] It survives in les us et coutumes “traditional usages”, recorded about 1207 in Villehardouin,[8] and in Noël du Fail in 1585 (selon les us et coustumes du pays).[2] Pomey already called it an old word in 1671.[2] In law, Littré describes it as a term for usages, nearly always joined with coutumes.[7]

Word family

Usage notes

In les us et coutumes the ⟨s⟩ is sounded in liaison.[6][7] Littré held it silent before a consonant and called the Académie's sounding of it in every position an error.[7] A separate, now obsolete us (Molière, 1661) comes from the ending of Latin masculine nouns of the second declension such as dominus: a savant en us was a scholar who Latinised his name out of pedantry, as in Molière's line Non pas de ces savants dont le nom n'est qu'en us (Les Fâcheux).[9][5][7]
