Neither...nor...

Neither you nor I ____able to work out this math problem.

A. am B. is C. are

Which one is the correct choice?

Thanks.

Some people say ‘is’, others say ‘are’.
It depends on whether you are classing ‘you’ and ‘I’ as independent entities or one combined group.

I’d say ‘neither’.

Correct answer: A. am (The verb most usually agrees with the subject that precedes it in such contexts)

I think it’s a ‘traditional rule v usage’ case, which has decently been covered here: usingenglish.com/forum/thre … either-nor

english-test.net/forum/ftopic23794.html also had their say in it.
Enlightening stuff.
