Ultimate origin
Latin (statuō)

Pronunciation

  • IPA (Classical): [ĩːˈstɪ.tu.oː][1]
  • IPA (Ecclesiastical): [inˈstiː.tu.o][1]

Forms

īnstituō (present infinitive īnstituere, perfect active īnstituī, supine īnstitūtum); third conjugation[1]

Etymology

It is from in- (“in, on”) and statuō “to set up”, with the vowel weakened to ⟨i⟩.[2][1][3]

Earliest recorded meaning

The OLD's first citations are from Plautus, of setting an activity going and of establishing ceremonies.[2] Plautus also has an old perfect instituīvī.[4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to put or place in, as Plautus' arguments set up in the mind, to set in operation, organize, to build, and to raise a military force, as in Caesar.[6][2] It meant to establish formally an institution or ceremony, to fix a standard, to appoint someone to an office, or as heir, and to originate a custom or set a precedent, as in Cicero.[2] It meant to start on a task, as in Varro and Terence.[2] It also meant to train, instruct, educate, and to teach a subject, as in Quintilian.[2] Döderlein says īnstituere establishes a secular institution, īnstaurō a sacred or important one.[7]

In Ecclesiastical Latin it meant to ordain, establish, instruct.[8] It survives in French instituer and Spanish instituir.[1] English institute came from its participle in the early 14th century, and English institution from īnstitūtiō about 1400.[3]
