The word 'rapidity' is used to talk about how fast something is happening or how quickly something is taking place. For example, if you say "The car accelerated with rapidity", it means that the car started moving very fast. Another example could be "The firefighters responded with rapidity to the emergency call", which means that they arrived quickly to the scene. It is a more formal word and is often used in professional or academic settings.
