Pronunciation

  • Classical: [ɪnˈwɪ.ɡɪ.ɫoː][1]
  • Ecclesiastical: [iɱˈviː.d͡ʒi.lo][1]

Forms

invigilō (present infinitive invigilāre, perfect active invigilāvī, supine invigilātum); first conjugation[1]

Etymology

It is from Latin in- + vigilō (“to keep awake, watch”).[2][3] The simple verb is made from vigil (“awake; watchman”), which de Vaan lists beside vigeō (“to thrive”) and considers certainly cognate with vegeō (“to rouse”).[4]

Earliest recorded meaning

The TLL finds it from Cinna (doubtfully), Cicero and Virgil on;[2] Cicero says in the Philippics that he had kept watch over the state (invigilāsse reī pūblicae).[5][6]

Semantic evolution

Its plain sense is to stay awake: Celsus uses it of someone who stays awake a little and then sleeps well, and Ovid of lying awake in suffering.[5][7][8] With a dative it means to stay up working over something; in a wider sense it means to watch over something with care: Virgil's bees are intent on getting food, Pliny the Younger speaks of watching over the public good and Ulpian of attending to an inheritance.[5][7][9] Cinna uses the participle invigilātus of poems produced by nightly study by lamplight.[5][8] Lactantius uses it of guarding houses.[6] Its participle gave English invigilate, recorded from the 1550s, which in the late 19th century came to be used of watching over students at examinations.[10]
