Forms

īnstitūtum n (genitive īnstitūtī); second declension[1]

Etymology

It is the neuter of īnstitūtus, the past participle of īnstituō “to set up, establish”, used as a noun.[2][1][3]

Earliest recorded meaning

The OLD's earliest citation is from Cato, of a planned course of action.[2] Köbler's first source is Cicero; he dates Cato 234–149 BC.[4]

Semantic evolution

It meant an intended course of action, a plan, as in Cato and Cicero.[2][5] It meant an established practice, custom, ex īnstitūtō by custom, as in Vitruvius, and in Cicero the practice of a group, a way of life, and in the plural teachings, precepts.[2] Caesar's īnstitūtō Caesaris means by Caesar's practice.[5]

In Ecclesiastical Latin it meant a precept, custom, regulation, plan, mode of life, institution.[6] Medieval Latin used it for a legal provision, rule, ordinance, an order and a writ.[7] It survives in Italian istituto and French institut, and English institute came as a noun in the 1510s, “purpose, design”.[1][3]
