对某人下诺言英语怎么说

To make a promise to someone in English, you can say "I promise" or "I give you my word." The phrase "I promise" is commonly used to convey a commitment or assurance, while "I give you my word" is a more formal way of expressing a promise.
The phrase "I promise" comes from the Old English word "promise," which means "to give one's word" or "to make a declaration." In modern English, "promise" is a verb that means to commit or assure someone that you will do something.
Here are some examples of how you can use "I promise" or "I give you my word" in a sentence:
"I promise to be home by 10pm." (This means that you are committing to being home by a certain time.)
"I give you my word that I will return the money by tomorrow." (This is a more formal way of saying that you will return the money.)
"I promise to help you with your homework." (This means that you are committing to helping someone with their homework.)
"I give you my word that I will keep your secret." (This is a formal way of saying that you will keep someone's secret.)
