Etymology: Bugbane is a compound of two plain English words: "bug," meaning an insect or small creeping creature, and "bane," an old word for a poison or a ruin, something that destroys or harms. Put together, the name says exactly what the plant is supposed to do, which is ruin life for insects. The plant it names is a North American and Asian perennial, prized in gardens for its tall spikes of white flowers. The compound is transparent in a way many plant names are not. "Bane" survives mostly in fixed phrases such as "the bane of my existence" and in names like "wolfsbane" and "ratsbane," which likewise name poisons. Bugbane follows that pattern, pairing a creature with the word for its destroyer. Its meaning depends entirely on that older sense of "bane" as a harmful agent rather than the modern sense of an annoyance.
