Pronunciation

Forms

outil m (plural outils)[1] Old French ustil, hustil and ostil (12th century), then oustil (about 1268), and outil from 1538.[2][3][4] In the 16th century it was often util, after the adjective utile, a form still used in some dialects of the East and South-West.[5]

Etymology

It is inherited from Old French ostil, inherited from Vulgar Latin *usitilium, the singular of a neuter plural *usitilia, an alteration of Classical Latin ūtēnsilia (“necessary things, furniture, utensils”).[6][4][7][2] The classical word is the neuter plural of the adjective ūtēnsilis (“useful”), from ūtor (“to use”).[3] A crossing with the Latin verb behind user would explain the ⟨s⟩ of the Vulgar Latin plural, but not the shortening of the long initial vowel of the classical word;[6][4][5] the GLLF instead takes the alteration from ūsitor (“to use often”).[3] Late Latin forms beginning with ⟨os-⟩ are recorded from the 8th and 9th centuries.[6][4]

Bloch and Wartburg note that the word is found only in French and in some dialects of northern Italy.[5] ustensile is a learned word from the same Latin source.[4][2]

Earliest recorded meaning

The first record, in the Voyage de saint Brendan (early 12th century), is the plural ustilz, the equipment and necessaries taken on board for a voyage.[6][4]

Semantic evolution

The modern sense, a made object used to do a piece of work, is found in 1174 in Guernes de Pont-Sainte-Maxence and has remained the usual one.[6][4] A popular sense “male member” is recorded from the 13th century and has survived, while Montaigne's use for any organ of the body (about 1580) has not.[4][6]

In the 13th century the word took the figurative sense “means of action” (before 1272).[6][4] It was said of a person who serves as another's instrument (before 1615) and, in familiar use, of a clumsy or incompetent person (1808), uses now archaic.[6][4] The industrial age gave machine-outil (1857), and linguists use mot-outil for a grammatical word (1922).[4] Rey notes that outil is no longer felt to be linked to ustensile, though it stays close to it and to instrument in meaning.[4]
