Cobwebs and spider webs are different things. Spiderwebs are spun from their silk, and you will usuallysee the spider at home in the web. Cobwebs are a mixture of dust and whatever glues the dust together-sorry-I can't be more specific on that part.
Best Answer: It's an old English term. it was called Coppeweb originally. Coppe, spider and coppe was head. It was short for the original term attercoppe. Ator was poison and coppe was head. Coppe came from the English mother tongue German and Kopf meant head.The English shortened it to kopfweb. It is further changed to cobweb.'ve wondered this myself. I think that maybe a spider web is what a spider is living in. A cobweb is what's left after the spider moves away. Since the spider is no longer keeping up the web it falls into disrepair and gets all dusty -- and becomes a cobweb.
