- hellebore (n.)
- late 14c., from Old French ellebore, from Latin elleborus, from Greek helleboros, the name given to various plants of both poisonous and medicinal qualities, reputed to cure madness; of uncertain origin. Perhaps literally "plant eaten by fawns," from Greek ellos/hellos "fawn" (from PIE *elno-, extended form of *el- (2) "red, brown," in animal and tree names; see elk) + bora "food of beasts," from bibroskein "to eat," from PIE root *gwere- (4) "to swallow" (see voracity).
