Tongue twisters are words or sentences which are difficult to say. Here are some famous examples: - She sells sea-shells on the sea-shore. - Peter Piper picked a peck of pickled pepper. As you see, tongue twisters very often have words which start with the same letters. Write some tongue twisters of your own. You get a point if your teacher can't say them without making a mistake! 1. 2. 3.
