Full origin of as soon as possible →Frequently asked questions
What is the difference between as soon as possible and immediately?
Immediately means right now, with no delay at all. As soon as possible allows for real constraints, so it means the earliest point at which the person can realistically act, which might be later today or tomorrow.
Is ASAP rude?
It can be. Because it is short and urgent it often reads as a demand, especially without a please or a deadline. Naming an actual date and time is usually clearer and lands better than ASAP.
