PARRICIDIUM

parricidium (par-[schwa]-sid-ee-[schwa]m), n. [Latin] Roman law.

1. The murder of a near relative, esp. a parent.

2. Perhaps in ancient law, the murder of any free citizen. • This ancient, broad sense of parricidium gave way in pre-Imperial law to homicidium (homicide), which extended to the killing of a slave.
