You may remember that people used to worry about what the word was for the fluff that one finds in the corners of one's pockets. Sometimes people invent words for things that have long gone un-named: Gelett Burgess though up blurb for the self-promoting material on a book jacket; someone came up with gridlock (and pedlock, but the latter did not catch on). And some people seem to know the name for everything; the little decorative thing that screws on at the top of a lamp to hold the shade on is a finial, and it screws onto the top of the harp.
