What does it mean when a sportscaster says "It's all academic" at the tail end of a sports contest? Can you cite an example? Thank you.
In any context, it means "It doesn't matter now" or "That makes no difference to the matter currently under discussion". In the sports context, it might refer to something like a team suddenly starting to play well towards the end of a match but, by then, it's too late, because the other team is so far ahead that the result is pretty much decided.
Here's a couple of other contexts:
Me: I've cancelled my party on Saturday evening.
Friend: What? But I've bought a new dress.
Me: Sorry.
Friend: And I've told my boyfriend he can come.
Me: Right.
Friend: I was really looking forward to it.
Me. OK. Well, I'm sorry but it's all academic now. I've cancelled it!
John: I want to go on holiday to Spain this year.
Jane: I've already booked our holiday. We're going to Cornwall.
John: But I want to eat tapas, drink rioja and watch flamenco.
Jane: I'm sure you do, darling, but that's academic. We're off to Cornwall for a couple of weeks of beer, pasties and rain!
