rapidly
In great haste
Rapidly means quickly or at high speed.
Events that unfold rapidly happen in swift succession: The situation rapidly deteriorated.
Something growing rapidly expands at a fast rate.
The word emphasizes pace rather than mere quickness—rapidly suggests continuous, sustained speed rather than a single quick action.
