Is it okay to say "What does your family usually do on A Sunday?" ???
Would it be incorrect if I said: "What does your family usually do on Sunday?" with no indefinite article here? I've looked through Swan's PEU and, apparently, there's no mention concerning this, say, grammatical aspect.
If there is any difference in meaning between these two could anyone explain it to me PLEASE? Thank you in advance!
I spent a few hours at the gym on Sunday (or this Sunday). (past)
I'll see you on Sunday (or this Sunday). (future)
You could also say, I'll see you on a Sunday, which means on one Sunday in the future, but not the Sunday that is nearest in time (not this Sunday).
So if you wanted to say that you were born on a particular day of the week, you would say I was born on a Sunday.
