Pronunciation

  • Classical: [paːr.rɪˈkiː.di.ũː][1]
  • Ecclesiastical: [par.riˈt͡ʃiː.di.um][1]

Forms

parricīdium n (genitive parricīdiī or parricīdī); second declension[1]

Etymology

It is formed from parricīda (“murderer of a near relative”) with the suffix -ium.[2][3][1] The origin of ⟨parricīda⟩ is uncertain: de Vaan thinks the first part was ⟨*pāri-⟩, with ⟨-rr-⟩ as in Iuppiter, and finds pār (“equal”) the most obvious source, giving “who kills an equal”; he rejects a link with Ancient Greek πηός (pēós, “kinsman by marriage”).[4] The second part is ⟨-cīda⟩ “killer”, from caedō (“to cut, kill”).[1][4] Ancient writers derived it from the killing of a parent or of an equal.[3] The OLD notes that the sense “murder of one's father” owes much to a mistaken link with pater (“father”).[2]

Earliest recorded meaning

Plautus calls a man “full to the brim of fraud, crime, parricide and perjury” in the Rudens.[2]

Semantic evolution

It is the murder of a near relation, especially of one's father or parents, as Cicero's “the parricide of his father and uncle”, and of other kin, as in an unnamed tragedy.[2][5] It is also murder or assassination, usually of a friend or superior, and especially of the head of the state: Valerius Maximus says Cassius should never be named without “public parricide”, and Suetonius reports that the Ides of March were named Parricīdium.[2] With patriae it is the betrayal or ruin of one's country, as in Cicero's Pro Sulla, and alone treason or rebellion.[2][5]

Köbler finds it in the capitularies, councils and the Frisian and Visigothic laws.[6]
