This question already has an answer here:
Nobody from the Police Department and nobody from the Fire Department is/are going to the rescue.
Which verb agreement is grammatical or preferable for other reasons?
- Everyone that you know and everyone that you don't know is/are going to be there.
- Anything you read and anything you hear affects/affect you.
I have read that if parts of a compound subject are joined together by the conjunction and, then one should use a plural verb. But in these examples with indefinite pronouns, I feel like a singular verb should be used.
Another rule on verb agreement with compound subjects: When using or, either/or, or neither/nor, the compound subject might be singular or plural. Generally, if all elements are singular, then the compound subject should be treated as singular.
But again it doesn't cover use of indefinite pronouns with and.
