do have a passing interest in what's going on in sports, and that's where I come in. I always tailored my TV sportscast so that non-fans could understand it and ended each by saying “..and That’s Sports”.'
That's sport and that's sports mean to me the same thing or so. - Eg Fans have just watched a football match and their lovely team have not won. They all say that's sports/that's sport. =>
-That's sports would mean that is the same in any sport (ei similar comparing with other sports), there are always winners and loosers.
-That's sport meaning that is part of sport, there are always winners and loosers
By the way, that's sport has to me the same kind of meaning of the idioms that's life and that is it.
However, I must admit that's sports seems uncorrect but might be commonly used in spoken English - what about it?
As a non-native speaker of English I take your words but try to figure out why both that's sport and that's sports are used.
