Verb

dēmōnstrō (present infinitive dēmōnstrāre, perfect active dēmōnstrāvī, supine dēmōnstrātum); first conjugation

I show, demonstrate, prove
- 426 CE, Aurelius Augustinus Hipponensis, City of God 12.1:
  Sicut ergo, cum uitium oculorum dicitur caecitas, id ostenditur, quod ad naturam oculorum pertinet uisus; et cum uitium aurium dicitur surditas, ad earum naturam pertinere demonstratur auditus: ita, cum uitium creaturae angelicae dicitur, quo non adhaeret Deo, hinc apertissime declaratur, eius naturae ut Deo adhaereat conuenire.
  As, then, when we say that blindness is a defect of the eyes, we prove that sight belongs to the nature of the eyes; and when we say that deafness is a defect of the ears, hearing is thereby proved to belong to their nature;—so, when we say that it is a fault of the angelic creature that it does not cleave to God, we hereby most plainly declare that it pertained to its nature to cleave to God.
