Cách sử dụng
The expression "one and only" is typically used to refer to someone or something that is unique and irreplaceable. For example, if you say that your best friend is your "one and only" friend, you mean that there is no other friend in your life who is as important or close to you as they are. Similarly, if you say that your grandmother's recipe for apple pie is your "one and only" favorite dessert, you mean that you have never tasted any dessert that you enjoy more than that particular recipe. Essentially, "one and only" emphasizes that the person or thing being discussed is very special and stands out from all others.
