Etymology

Origin of gossamer

First recorded in 1300–50; Middle English gos(s)esomer, gossummer “filmy substance made of cobwebs; fine filament; something trivial”; possibly first used as a name for late, mild autumn, a time when goose was a favorite dish (compare German Gänsemonat “November”), then transferred to the cobwebs frequent at that time of year

Explanation

Gossamer is something super fine and delicate — like a spider web or the material of a wedding veil. The original gossamer, from which these meanings come from, is the fine, filmy substance spiders excrete to weave their webs. A dress can be gossamer-like, if its fabric is so sheer as to be see-through, or almost. Your chances of going to a good college are "gossamer thin" if you've never cracked a book in high school.
