Cách sử dụng
"As and when" is an expression that means "at the appropriate time and only when it is necessary or possible." It can be used in situations where something is not scheduled or certain, but it may happen later on. For example, you might say "I'll finish the report as and when I have enough information" or "We'll plan the party as and when we know everyone's availability." Essentially, it is a way of saying that you will do something when the conditions are right or when the situation calls for it.
