I like playing badminton.
Me too, I play it every Friday. What kind of sport is it?
It is a racquet sport.
I see, and when does it have its origins?
It was developed in British India for the earlier game of battledore and shuttlecock.
That does sound interesting. What else do you know about badminton? 
It is often played as a casual outdoor activity.
I think thats because its mostly played outdoors. Right?
