Cách sử dụng
The expression "needless to say" is used when you want to emphasize that something is so obvious or well-known that it doesn't need to be explained further. You might use this phrase in a conversation or in writing when you want to convey that everyone already knows something. For example, if you were talking about an important historical event, you could say "Needless to say, it had a significant impact on our world today." This lets the listener or reader know that the impact is already widely accepted or understood.
