The rule is simple: singular subjects take singular verbs and plural subjects take plural verbs. But sometimes it’s difficult to tell whether a subject is singular or plural. That’s why subject and verb agreement errors crop up in so many pieces of writing. Making matters worse is the fact that most people don’t know what subject and verb agreement means. In fact, too many people don’t know a subject from a verb.When you’re fixing up your sentences and making sure they are correct, it helps to know the parts of speech, how to conjugate a verb, and how to diagram a sentence (so you can identify the subject). If you understand all those basic elements of language, then you can easily make sure your subjects and verbs agree.
