Etymology and origin of the Latin word homicida
Etymology tree
Forms
homicīda m or f (genitive homicīdae); first declension[1] It is masculine, and also feminine of a woman.[2][1]
Etymology
It is from Latin homō (“man”) + -cīda (“killer”), the second part from caedō (“to cut down, kill”), formed like parricīda.[3][4][5] De Vaan traces caedō to Proto-Italic *kaid-e/o- and Proto-Indo-European *keh₂id- (“to cut, hew”).[6]
Earliest recorded meaning
De Vaan and Köbler date it from Cicero,[6][7] who asks whether certain men are murderers or liberators, homicidaene sint an vindices libertatis.[3][2]
Semantic evolution
It is a manslayer or murderer.[3][2] Döderlein notes that it denotes the killer in general, as far as killing is a crime, like Greek ἀνδροφόνος (androphónos), whereas interfector is the slayer of a particular person.[8] Horace uses it of an epic hero as a killer of men, homicīdam Hectorem.[3] It is common in the Germanic law codes of the early Middle Ages.[7] Church Latin has it as murderer.[9] English homicide in the sense “person who kills” (late 14th century) came from it through French.[5]
