Pronunciation

  • Classical: [hɔ.mɪˈkiː.di.ũː][1]
  • Ecclesiastical: [o.miˈt͡ʃiː.di.um][1]

Forms

homicīdium n (genitive homicīdiī or homicīdī); second declension[1]

Etymology

It is from Latin homicīda (“man-slayer”) with the suffix -ium, as parricīdium goes with parricīda.[2][3][4] Wiktionary analyses it as from Latin homō + -cīdium.[1] Isidore of Seville explained it as made of homō and caedēs “slaughter”.[3]

Earliest recorded meaning

The TLL finds it first, and often, in the elder Seneca's declamations, then once each in Valerius Maximus, Petronius and Pliny the Elder and three times in Seneca the philosopher.[3] Köbler's first source is Seneca.[5]

Semantic evolution

Lewis and Short call it post-Classical; its sense was always the killing of a human being, manslaughter or murder.[4][3] Quintilian uses it of a charge of homicide in court, and Tacitus has it in the Germania.[4][6] The TLL notes that it was usually done with a weapon and only rarely by poison, and that the plural appears from Seneca on;[3] Tertullian lists the sword, poison and magic spells as its means.[3] A feminine homicīdia is found in an Old Latin Bible manuscript.[3]

In the Church it meant murder.[7] Medieval Latin also used it for the fine paid for a killing and for slaughter in war;[8][9] English legal writers such as Glanvill distinguished secret killing (murdrum) from simple homicīdium.[9] It survives in Italian omicidio.[6]
