Cách sử dụng
The phrase "if and when" is used to express uncertainty about whether or when something will happen, but suggests that it might happen in the future. For example, if you are talking about a job offer, you might say "I will accept the job offer if and when it is given to me." This means that you are willing to accept the job, but only if you actually receive an offer. It is a way of putting conditions on your agreement, without completely rejecting the possibility altogether.
