Usage

What does cobweb mean? Cobweb is another word for a spider web. But cobweb is most commonly used to refer to the kind of dusty old spider webs that hang in the corners of places that haven’t been used or cleaned in a long time, like attics and abandoned houses. For that reason, cobweb is often used in expressions like clean out the cobwebs, meaning to do something to clear your mind or make it function normally again, perhaps after a period of inactivity or confusion. Cobweb can also be used as a verb, meaning to cover in cobwebs, as in No one had entered the study for years, and spiders had cobwebbed the entire bookcase. Example: The abandoned house was dusty and full of cobwebs.

Etymology

Origin of cobweb

1275–1325; Middle English coppeweb, derivative of Old English -coppe spider (in ātorcoppe poison spider); cognate with Middle Dutch koppe; see web

Explanation

A cobweb is the net of sticky threads that a spider weaves to catch insects. You can also call a cobweb a spider's web. A cobweb is any spider's web, although some people use it to specify the dense, tangled type of web that certain spiders weave, or to mean a dusty old web, like the ones you might see in your grandparents' attic. Cobweb can also describe some intricate or complicated things: "She got lost in the cobweb of unfamiliar subway lines in the city." It comes from the Old English coppeweb, from the now-obsolete coppe, "spider."
