There are many times when you want or need to negate, refuse, or just plain say no to something. When the waiter asks you if you'd like to order more food, you might be too full. If a friend invites you out on a night when you already have plans, you'll need to kindly refuse and possibly suggest an alternate plan. Those types of situations are covered in this chapter; you'll learn how to make negative sentences, become familiar with common negative expressions, and discover how to distinguish between the negative and the positive.
