Centuries before its breezy emergence as an adjective meaning "extremely light or delicate," gossamer was used as a noun. It came to our language by way of Middle English, where gossomer (literally "goose summer") referred to a period of mild weather in late autumn or early winter. Gossomer was also used in Middle English as a word for filmy cobwebs floating through the air in calm, clear weather, possibly because somebody thought the webs looked like the down of a goose or because that mild period was when they tended to notice the spider silk wafting. This sense eventually inspired the adjective gossamer, which describes things that are as light or delicate as cobwebs. The noun form of gossamer is still floating around: it has held onto its Middle English predecessor’s meaning of "a film of cobwebs" and can also refer to something that is light, delicate, or insubstantial, as in "a thread of gossamer."
