Etymology: Aconitine takes its name from its plant source. The word "aconite" comes from Latin "aconitum", the name for the monkshood or wolfsbane genus, and the chemical suffix "-ine" is the standard ending chemists attached to alkaloids isolated from plants. So the name is a straightforward compound: the poison is named for the flower that carries it, marked as a basic nitrogen compound by the ending. The plant itself has a long reputation. Monkshood was prized and feared for centuries, and it was associated with wolves, which is why one of its common names is wolfsbane. The same plant has yielded both medicine and murder, and the alkaloid is the reason: even small amounts disrupt the heart and nerves, yet tiny doses were once used against pain and inflammation. The word follows the plant rather than a discovery story. Its meaning rests on the plant's role, so the name tells you where the substance comes from before it tells you what it does.
