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.
