Lips help you make sounds 😜

In the development of linguistics, humans evolved muscles and lips useful for articulation.

By bringing our lips together we can form the sounds associated with the letter “p”, “b” and “m” (go ahead, I did it too).

Bringing the central incisors of the maxilla (upper jaw) to our bottom lip, we can form the sounds of the letters “f” and “v”. The sounds of “r, y, and w” are also possible in thanks to lip movement.
