This is an amusing and confusing list of expressions in English that adult ESL students often think should have similar meanings and don't or opposite meanings and don't. For example, we call the third hand on a watch or clock "the second hand". Why? It's fun to discuss these in class and ensure that students don't misuse them. For example, I once asked a student why he was late. He responded, "I slept over." "Really?", I asked. "Where?" Needless to say, he was perplexed because he had meant, "I overslept." Many other handouts, including this one, are contained in my book, "Let's Look At It This Way!", which is available in my store. It's actually a pretty good deal. For the cost of a few handouts, you get 50+ to reproduce for your instructional and classroom use.
