Forms

vigilanter (comparative vigilantius, superlative vigilantissimē)[1]

Etymology

It is from Latin vigilāns (“watchful”) + -ter,[2][3] from the present participle of vigilō (“to keep awake, watch”);[4][5] Köbler traces it to vigil (“awake, watchful”).[5]

Earliest recorded meaning

Its first recorded use is in Cicero,[5][6] who uses it of looking after oneself and of governing a province with alert care.[3]

Semantic evolution

Cicero uses all its degrees: he promises to strive more vigilantly (ēnītar vigilantius), urges that Antony be guarded against more carefully and more vigilantly, and speaks of someone being harassed most vehemently and most vigilantly.[3][6][7] Ammianus Marcellinus pairs it with fortiter, and Augustine and the jurists of the Digest also use it.[3][7]

Medieval writers kept it for watchfulness, as Bede does of fighting vices and Peter of Blois of guarding a vineyard.[8] The Chronicle of Fontenelle uses it for “wisely, prudently”.[9]
