Etymology

The word "bane" traces back to Old English bana, meaning "slayer" or "cause of death," reflecting its grim association with destruction. Over time, it evolved metaphorically to denote anything causing ruin or extreme annoyance, while retaining its archaic sense of "poison." The silent "e" is a vestige of Middle English spelling conventions.
