Forms

instruire[1] Old French enstruire (12th century); the form instruire from the late 14th century, with the participle instruit from 1346.[2][3][4][5]

Etymology

It is borrowed from Latin īnstruō (“to build in, equip, teach”), first taken in the Frenchified form enstruire and remade with a Latinised prefix from 1346.[2][5][4][6] Its ending follows construire and détruire, unlike verbs such as instituer.[2][6] Old French also had estruire (“to build”) (about 1175), which kept the older Latin senses, while the borrowed verb took the sense “to teach”, which arose in Latin under the Empire.[2][5] Wiktionary instead treats the verb as inherited through the Old French forms, with the prefix relatinised.[1]

The Latin verb is formed from in- and struō (“to lay in layers, arrange, build”),[5][4][3] whose base Rey links, perhaps, to Proto-Indo-European *ster- (“to spread”).[5] Compare Spanish instruir and Italian istruire.[7]

Earliest recorded meaning

It is first found as enstruire in the Oxford Psalter (first half of the 12th century), meaning to form someone's mind by precepts and lessons.[2][3][5]

Semantic evolution

About 1200 instruire quelqu'un de quelque chose meant to make someone acquainted with a fact or piece of knowledge.[2][5] From the late 14th century a thing could be the subject, in the sense “to teach a lesson”, as in Eustache Deschamps.[2][5] The participle bien or mal instruit meant “well” or “badly brought up” in 1346; since the 18th century instruit has meant “learned”.[5][2] The pronominal s'instruire is found in Montaigne (1592).[2][7]

In the 16th century it entered law: Robert Estienne records instruire un procès in 1549, to prepare a case for judgement.[2][5] The sense “to give instructions to” (1672, Boileau) has gone out of use, and Bossuet used it in 1677 for training an animal.[5][2] Bloch and Wartburg see the legal sense as a French development.[6]
