You know how to sound intelligent. You just sprinkle a lot of big words into your speech. You study the dictionary, learn how to pronounce them if you think that's absolutely necessary, and then stun people when you drop them into your conversation like vocabulary bombs. Who cares if you don't know what they mean? Chances are good the people you use them with are just as clueless as you. They won't dare say anything. So keep on keeping on. Wear this tee and have an etymology day.
