Cách sử dụng
"If not" is an expression that is used to suggest an alternative if the first option does not work out. For example, if you plan to go to the beach but the weather is bad, you can say "Let's go to the park, if not the beach." This means that if the beach does not work out due to the bad weather, you can go to the park instead. The expression can also be used to emphasize a negative outcome. For example, if you say "I studied really hard for the test, if not, I will fail," it means that if you do not pass the test even after studying hard, then you will fail.
