Forms
perduellis m (genitive perduellis); third declension[1] An old genitive plural perduellum occurs in Accius.[2][3]
Etymology
It is from Latin per- + duellum (“war”), the old form of bellum.[2][4][1] The TLL suggests that the form with ⟨du⟩ survived because perduelliō had become a legal term, comparing rebellis beside rebellō; de Vaan reports Meiser's view that legal terminology preserved it.[4][5]
Earliest recorded meaning
It is found from Plautus on,[5][4][6] in elevated language:[4] the Amphitruo tells how its hero defeated the enemy.[4]
Semantic evolution
In early Latin it was the word for a foreign enemy at war with one's own people;[2][3] Plautus also transfers it to a private enemy in the Pseudolus.[7][8] Ennius and Accius use it, and Livy keeps it in formal language such as a solemn prayer of Scipio and a decree of the senate.[4][3] By Cicero's time it was archaic: Varro explains that hostis, once “foreigner”, had come to mean what the ancients called perduellis, and Cicero notes in the De officiis that the milder hostis had replaced it.[4][3] After Cicero it appears mainly where the meaning is explained or old language is imitated;[4] later it was revived in a sense mixed with that of perduelliō, “traitor, rebel”, twelve times in Ammianus Marcellinus.[4]
Glossaries explain it as an enemy or warrior.[4] In British medieval Latin it meant an enemy, a fighter, and as an adjective hostile or rebellious.[9]
