Good grid, shouldn't have so poor a rating. But demanding that I type in "homograph" seems too harsh - I got the connection but expressed it in some form like "they can be verbs or nouns." As well as guessing all the other homo-words, lol. Tough word categories as well - maybe too many for one grid? Not about to do what some people on this site do and give a bad score because *I* don't know what a Rock Island is, though.

Funny how to an Only Connect fan the British slang words jump out!
