Pronunciation

  • Classical: [ˈkɫaː.roː][1]
  • Ecclesiastical: [ˈklaː.ro][1]

Forms

clārō (present infinitive clārāre, perfect active clārāvī, supine clārātum); first conjugation[1]

Etymology

It is from Latin clārus (“bright, clear”) + -ō.[2][3][1] The adjective goes back to Proto-Italic *klāro- (“loud”) and Proto-Indo-European *klh₁-ro- (“loud, sonorous”).[4]

Earliest recorded meaning

De Vaan dates it from Ennius,[4] whom Nonius quotes for an intransitive use.[2]

Semantic evolution

In Classical Latin it is a rare, mostly poetic verb.[5] Cicero's verse uses it of a constellation marking the start of summer and of Jupiter showing his sceptre on a high column;[2][5] Statius of a meteor lighting up its path with a long trail of flame.[2][5] Lucretius uses it of making a subject clear in verse: animi natura videtur atque animae claranda meis iam versibus esse “the nature of mind and spirit, it seems, must now be made clear in my verses”.[2] Horace uses it for making famous: illum non labor Isthmius clarabit pugilem “no Isthmian toil will make him famous as a boxer”.[2][5] Medieval writers used it for showing plainly, and reflexively for a person appearing in a vision.[6]
