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 meanings using the word “mouth”. But some of them are not so nice.

For example, if you say bad things about a person, the person might protest (抗议) and say “Do not bad mouth me.”

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

Sometimes when one person is speaking, he says the same thing that his friend is going to say. When this happens, the friend might say, “You took the words right out of 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.
