People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions about the word “mouth”. But some of them are not so nice.

Sometimes, people say something to a friend or family member that they later regret because it hurts that people's feelings. Or they tell the person something they were not supposed to. The speaker might say: “I really put my foot in my mouth this time”. If this should happen, the speaker might feel down in the mouth, In other words, he might feel afraid for saying the wrong thing.

When this happens, the friend might say: “You took the words right out of my mouth!” Sometimes a person has a bad or unpleasant experience with another person. He might say that experience “left a bad taste in my mouth”. Or the person has possibly had a very scary experience, like beingchasedby an angry dog. He might say, “ I had my heart in my mouth.”
Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person “was born with a silver spoon in his mouth”. This rich person is the opposite of a person who lives from “hand to mouth”. This person is very poor and only has enough money for the most important things in life, like food.
