infanticide

The word 'infanticide' is a direct borrowing from Late Latin infanticidium, which itself was formed from the classical Latin elements infans ('infant') and -cidium ('a killing'). The root caedere, meaning 'to cut down' or 'to strike', is a potent Proto-Indo-European derivative, giving rise to many English words concerning decisive cutting or killing, such as 'homicide' and 'decide'. In its original Latin context, the compound explicitly named the act of destroying a young child. This literal, grim combination was adopted into English in the 17th century to serve as the precise legal and sociological term for the killing of an infant, retaining the stark semantic logic of its ancient components.
