Pronunciation

  • IPA (Classical): [ĩː.struːˈmɛn.tũː][1]
  • IPA (Ecclesiastical): [in.struˈmɛn.tum][1]

Forms

īnstrūmentum n (genitive īnstrūmentī); second declension[1]

Etymology

It is from īnstruō “to build, equip” with the suffix -mentum.[2][1][3] Isidore defines it as that with which we build something, as a knife, a pen or an adze.[4]

Earliest recorded meaning

The OLD's earliest citation is from Cato, of the equipment for a trade.[2] Köbler's first source is Cicero; he dates Cato 234–149 BC.[5]

Semantic evolution

It meant equipment, tools, apparatus, collectively, as in Cato, a single tool, as in Varro, and the outfit or chattels of a person or place.[2][6] In Cicero it meant the means for a purpose, an instrument, and a person's mental equipment, and Verres' furniture.[2][7] In Quintilian it meant evidence on which a case rests, and a legal document, deed.[2]

In Ecclesiastical Latin it meant a tool, document, record, means.[8] Medieval Latin used it for a holy book, a part of Scripture, and teaching.[9] It survives in Italian strumento and Spanish instrumento, and English instrument came in the late 13th century, first of a musical instrument.[1][10]
