The condition of being prepared or ready for something.
Her readiness to help others makes her a great friend.
Readiness is formed from "ready" (from Old English "ræde", meaning prepared or willing) and "-ness" (a suffix indicating a state or condition). The word "readiness" refers to the state of being prepared or willing to do something.
Think of being 'prepared' ('ready') and the '-ness' indicating a state. This helps you remember that 'readiness' means the state of being prepared.
