If you have a bunch of odds and ends and get rid of all but one of
them, what do you call it?

You have the one remaining odd end, of course. One is an odd number. Two is an even odder number. Why do we pronounce one as though it has a "W" in it, and two as though it doesn't?

Why do some people live in so-called apartments when they're so close together? Why do some people live in flats that are three-dimentioned?
