This PowerPoint presentation covers the topic of subject-verb agreement. It explores some of the difficulties with subject-verb agreement and provides notes to help avoid errors. Some key points covered include: indefinite pronouns like everyone are always singular; verbs accompanying pronouns like all depend on whether the pronoun refers to something countable; and when either/neither act as correlative conjunctions, the verb agrees with the subject closest to it. The presentation aims to help writers properly apply subject-verb agreement rules in their own writing.
