IPA: /ˈpærɪˌsaɪd/
KK: /ˈpærɪˌsaɪd/
A person who kills their father, mother, or another close family member.
The story revolves around a parricide who struggles with guilt after committing the crime.
Parricide is formed from "parri-" (from Latin "parricida", meaning father or ancestor) and "-cide" (from Latin "caedere", meaning to kill). The word refers to the act of killing one's father or a close relative.
Think of 'killing' ('-cide') a 'father' or 'ancestor' ('parri-') — that's why parricide means the act of killing a parent.
