Confidence
Established
Formation
Derivation
First attested
190–159 BC, Terence
Ultimate origins
Latin (dē-)Proto-Indo-European (*gʷʰen-)

Pronunciation

  • Classical: [deːˈfẽː.sɔr][1]
  • Ecclesiastical: [deˈfɛn.sor][1]

Forms

dēfēnsor m (genitive dēfēnsōris, feminine dēfēnstrīx or dēfēnsātrīx); third declension[1]

Etymology

It is formed from dēfendō (“to ward off, defend”) with the agent suffix -tor.[2][1] ⟨dēfendō⟩ is dē- with an unattested ⟨*fendō⟩ “to strike”, from Proto-Italic *fendō and Proto-Indo-European *gʷʰen- (“to strike”).[1]

Earliest recorded meaning

Terence, Andria: aliquem esse amīcum et dēfēnsōrem eī, “that she should have some friend and protector”.[2][3]

Semantic evolution

With a genitive it is one who wards off something, as Cicero calls himself the averter of the Sicilians' disasters.[2][4] Usually it is a protector or defender, and in the plural a garrison (Caesar); Caesar also uses it of stakes set to protect a bridge.[2] It is a champion or supporter of a person or cause (Cicero: as he should have been the defender of Caesar's acts), and in law the advocate for the defence, or the defendant.[2]

In Late Antiquity the dēfēnsor cīvitātis was an official of Roman cities, and the dēfēnsōrēs regiōnāriī were officials of the city of Rome.[5] Gregory of Tours and the early medieval laws use the word.[3] Church Latin glosses it “defender”.[6]
