There are many meanings of mouth, but they all relate to the hole from which you eat, speak, and breathe.

Like the mouth below your nose, other mouths are openings or have something to do with speaking. The opening at the top of a jar or bottle is its mouth. The place where a river meets the ocean is the mouth of the river. It’s called mouthing off when you give someone lip or sass. You can mouth the words to a song without singing them. A mouth (or mouthpiece) is someone who speaks for other people, like a lawyer.
