Patricide? What Does it Mean?

Patricide is (i) the act of killing one's father, or (ii) a person who kills his or her father. The word patricide derives from the Latin word pater (father) and the Latin suffix -cida (cutter or killer). Patricide is a sub-form of parricide, which is defined as an act of killing a close relative.

Compare with parricide (the killing of any close relative), matricide (the killing of one's mother), filicide (the killing of a child by his or her parent), fratricide (the killing of one's sibling, in particular a brother-compare to sororicide), regicide (the killing of a monarch), suicide (killing oneself) and homicide (killing another person).
