Look it up!    Hey, when you run into a word you don't know, grab your dictionary. That's a rule you should follow in and out of class. It's a good habit to develop.      So, look up “tautology” or “conundrum” or whatever word you need to find in your handy, dandy American Heritage Dictionary. Or head to the World Wide Web for a dictionary link I found. (Believe me. It's quicker using the older method — reaching over and picking up the paperback dictionary. Just don't knock over your beer!) Home
