Oftentimes, in the midst of composing a paper, you’ll find that your spell check just doesn’t help (of all those suggestions in the drop-down box which one is right?) and only later do you discover, when your paper comes back, that you should have used effect instead of affect, or that you have erroneously substituted the word discreet for its nearly identical counterpart discrete. In any case, to avoid the scourge of red pen, students should refer to a Usage Dictionary when they have any doubts concerning the proper use of a word. What, you might ask, is a Usage Dictionary? Well, a Usage Dictionary differs from normal dictionaries in that it gives explanations instead of definitions, and shows specific examples of proper use. Paul Brians is a Professor at Washington State University and has created a handy little website called Common Errors in English Usage that is much like a usage dictionary. For those looking for fuller treatments on particular words nothing can beat the Merriam-Webster's Dictionary of English Usage where a typical entry spans half a page. We also have a collection of others here!
