Agreement refers to number—if you have a singular subject, you need a singular verb. Plural subjects take plural verbs. To achieve subject/verb agreement, first determine whether your subject is singular or plural, and then pair it with the correct verb form.
The following examples use the verb to be, which is irregular (I am, you are, he/she/it is, they are, I was, you were, he/she/it was, they were):
- Instead of: Tim and Fran is a great couple.
- Write: Tim and Fran are a great couple. (Tim and Fran is a plural subject that takes a plural verb.)
- Instead of: One of my friends are going to your school.
- Write: One of my friends is going to school. (One is a singular subject takes a singular verb.)
When it Gets Tricky
Agreement can be difficult to determine when sentences are complex, or when the subject is compound (made up of more than one noun). Common examples include sentences in which the subject follows the verb, and those beginning with there is/are, and here is/are. When editing your work, remember to first figure out whether your subject is singular or plural, and then match it to the correct verb.
- Instead of: There is too many meetings scheduled on Tuesday morning.
- Write: There are too many meetings scheduled on Tuesday morning.
- Instead of: Here are the report you asked me to write.
- Write: Here is the report you asked me to write.
When compound subjects are connected by and (pencils and pens; the ball, the bat, and the mitt), they are plural. When they're connected by or (World War I or World War II; biology, chemistry, or physics), they are singular. Confusion can set in when the nouns forming the compound subject are both singular and plural and connected by or. Here are two examples:
Lee or his friends are driving too fast.
Was it his friends or Lee who was driving too fast?
Both sentences are correct, because when you have a compound subject made up of at least one singular subject and one plural subject connected by or, the verb must agree with the subject that is closest to it. In the first case, friends is plural, so the plural verb are is correct. In the second, Lee is singular, so the singular was is correct.
