Compound antecedents.

Compound antecedents. Whenever a compound antecedent is joined by or or nor, the pronoun agrees with the nearer or nearest antecedent. If the parts of the antecedent are of different genders, however, this kind of sentence can be awkward and may need to be revised.

AWKWARD Neither Annie nor Henry got his work done.
REVISED Annie didn’t get her work done, and neither did Henry.

When a compound antecedent contains singular and plural parts, the sentence may sound awkward unless the plural comes last.
