Forms

instrument m[1][2]

The plural is mostly instrumens, also instrumenz.[4][3]

Etymology

It is borrowed from Latin īnstrūmentum (“furniture, equipment, tools”), derived from īnstruō (“to equip”).[5][6] The DEAF explains that the Latin word developed regularly into estrument, and that it also lived in French as a borrowing, probably from the second half of the 13th century.[1] The DHLF calls instrument of 1365 a remaking of the older form,[7] and Körting likewise says the word is learned everywhere in Romance, with the older form of Old French the exception.[8]

According to the DEAF, the senses of the Old French word, a tool of any kind, a means to an end, a musical instrument and a document with legal force, were already Latin, while the use for organs of the body appears later.[1] The Latin sense “Testament” goes back to the end of the 2nd century and continued in Christian and Medieval Latin.[1]

Earliest recorded meaning

The DEAF's first record of this form is the Roman du Mont Saint-Michel of Guillaume de Saint-Pair, of the third quarter of the 12th century in a manuscript of the second half of the 13th, where it names a musical instrument.[1][9] The older form estrument is recorded from 1113–1119 in Philippe de Thaon's Comput.[5][10]

Semantic evolution

In the 13th and 14th centuries the learned form spread through documents: a deed or notarial act from 1282, a tool or device from about 1314, and a means to an end from the same date.[1] The DEAF also records a person serving as someone's instrument in a manuscript of the second quarter of the 14th century, the organs of the body, the sexual organs from about 1365, and the Old Testament.[1] Oresme writes instrument in 1365,[5] and the DMF records the word for a tool, apparatus or engine.[11]

The FEW dates the general sense of a tool in Middle and Modern French from Oresme on,[12] and the TLFi dates the figurative sense of a person or thing that serves a purpose to about 1485.[5] The modern word is French instrument.[5]

Anglo-Norman

The AND has separate entries for estrument, first cited from 1113–1119, and instrument, first cited from the last third of the 13th century, with the spellings enstrument, instrement and instrumentiz.[10][3] Under instrument it records the senses of a weapon or engine, the Old Testament, and a formal document attested by a notary.[3] Etymonline dates English instrument to the late 13th century, first for a musical instrument, from Old French instrument and enstrument as well as Latin.[16]

Usage notes

Tobler–Lommatzsch refers instrument to its article estrument,[2] the DÉCT knows only estrument,[17] and the DEAF, the AND and the DMF treat the two forms separately.[1][3][11]
