Either/or and Neither/nor
Either/or and neither/nor connect two balanced words, clauses or phrases. They are called correlative conjunctions.
Singular or plural verb?
When two singular subjects are connected by either/or or neither/nor, use a singular verb.
Example: Either Sally or Peter is invited.
Example: Neither Sally nor Peter is invited.
If one of the subjects is plural, the verb agrees with the closest subject.
Example: Either the secretaries or manager decides the menu.
Example: Neither the bats nor the cat wakes me at night.
