I found this site some time ago when I was surfing the net. Having been brought up in a Catholic School where they were a little, uh - ANAL - about grammar and spelling and writing in ink within the margins, I have strong reactions to grammatical errors. In any case, I found this site that lists common english errors where you can look up phrases before you write them down so that you won't look like a fool. It also explains the origin of the words or phrases, and gives the correct usage. It's very useful in crossword puzzles, too! https://web.archive.org/web/20110515074252/http://www.wsu.edu/~brians/errors/errors.html#b Please be kind! Don't diagram my sentences for me on this one?
