Sportsbook or Sports Book?

Question

Which is it - one word or two? There can be only one grammatically correct way, yet I see it both ways all the time. I need the definitive answer and proof that you're right for Best Answer points!

Answer 1

It is one word. Sportsbook is correct. You may see it on some sites as 2 words, but technically, it is in the dictionary as one word.

Answer 2

Well just to be fair here Sports and Book are both in the dictionary as well :)  However in the industry it's generally referred to as "sportsbook."  It has nothing to do with grammar of course it's just a matter of popular convention.  As for "proof" do a google search on Sports Book and you'll see how many "sportsbook" sites come up.
