Cách sử dụng
The expression "of course" is commonly used in English to confirm or reaffirm something that is expected or known to be true. It can also be used to show agreement or to indicate that something is obvious. For example, if someone asks you if you can swim and you reply, "Of course!" this means that it is assumed or understood that you can swim. Similarly, if someone says, "It's raining outside," and you respond with "Of course it is," it means that the fact that it is raining is expected or obvious. The expression can be used in both formal and informal situations, but it is important to use it appropriately and not overuse it.
