The story of the word

Greek βολβός named an edible bulb, probably the tassel hyacinth, which Athenians ate pickled and credited with aphrodisiac powers. Latin took it as bulbus and English as bulb in the 1560s, for plants only. Glassblowers borrowed it for the swollen end of a thermometer, and from there it passed to the electric lamp, so a light bulb is named after an onion.
