Why “filicide” is a great word
FILICIDE — [Noun] The act of killing one's own child, or a person who commits such an act. From the Latin fīlius ("son") and fīlia ("daughter") + the English combining form -cide ("killer, killing"). First recorded in English 1655–65. Unlike infanticide, which confines the horror to the cradle, or patricide, which severs the past, filicide unwrites the future. It is the profound stillness of a small coat on its hook, a story deliberately and prematurely closed, and the courtroom where a parent is both defendant and mourner—a crime that dismantles not a past, but a possibility.
