Labialization

Okay, so you know how you can make some sounds with your lips, like when you blow a raspberry? Labialization is when a person uses their lips while making certain sounds, like saying the letter "w". It's like giving a little kiss with your lips as you make the sound. Some languages, like French and Korean, use labialization a lot to make different sounds. It's kind of like using your lips as an extra tool to talk!
