Hockey is a sport
I think I've seen hockey on TV. Don't you play it on ice or something?
they play in teams of two against each other 
Yeah, I'm pretty sure I've seen it. Isn't that where the players have long sticks and are shooting a puck?
There are many types of hockey such as bandy and ice hockey
I must have seen ice hockey. What is bandy?
The first word hockey was used in 1773
