a glass bubble that trapped lightning and called it a good idea.
means A rounded object, whether a glass globe that holds an electric light, an underground plant storage organ like an onion or tulip, or any swollen bulb-shaped part.
from From Latin 'bulbus,' meaning an onion or bulbous root, which itself borrowed from Greek 'bolbos' for the same — a plant whose fat, layered underground swelling became the template for the word. The botanical sense came first; the electrical light 'bulb' arrived in the 19th century, named simply for sharing that rounded, swollen shape.
