Last week you learned 20 different ways to say "yes" in English, and today you'll learn 20 different expressions for "no."
These are especially important to learn because we often want to be polite when declining an invitation or request – it sounds a little rude to just say "no."
Or maybe you want to add some additional information to the simple answer of "no" – a lot of today's expressions include extra meaning.
This is just a very small sample of the many ways we have to say "no" in English – there are many, many more!
