n.

early 14c., coppewebbe; the first element is Old English -coppe, in atorcoppe “spider,” literally “poison-head” (see attercop). Spelling with -b- is from 16c., perhaps from cob. Cob as a stand-alone for “a spider” was an old word nearly dead even in dialects when J.R.R. Tolkien used it in “The Hobbit” (1937).
