Cách sử dụng
The word "someone" is used to refer to a person or an individual, without specifying their name or identity. We use it when we don't know the person's name, or when we want to talk about people in general, without being specific. For example: "Someone is knocking at the door" means that some person we don't know is knocking. Or we might say, "I need someone to help me move this furniture," which means we are looking for a person (any person, it doesn't matter who) to help us. So, if you are not sure about the name of the person you want to talk about or if you are just referring in general things any person can do, you can use the word "someone".
