This document defines subject-verb agreement and provides rules for determining agreement between subjects and verbs. The main rules are:
- Singular subjects take singular verbs and plural subjects take plural verbs
- Collective nouns can take singular or plural verbs depending on whether the collection is viewed as a whole or as individuals
- Subjects joined by "and" or coordinating conjunctions can take singular or plural verbs depending on whether they refer to a single thing or multiple things.
