It might seem a trivial question but it occured to me whlie I was writing for an assignment.
I know if I put a pair of in subject place, I should use a singular verb e.g. A pair of shoes is there. Does it work the other way around too?
What subject suits this sentence, a singular or plural one:
.... is/are a pair of shoes.
This is confusing for me because on the one hand when you point at some shoes actually you're showing something that is originally a plural noun so it must be addressed as plural. On the other hand we want to use a pair of which is singular. So which is correct?
It's a pair of shoes.
They're a pair of shoes.
