Subject Verb Agreement
Subject verb agreement refers to the number of the subject and verb.You must use a singular subject with a singular verb and a plural subject with a plural verb. When this happens, we say that the subject and the verbagree. That is why it is called subject verb agreement.
Subjects will always be nouns or pronouns.
Here are some example sentences: (The subjects are bold, and the verbsare underlined.)
They are playing outside. (plural)
Mark runs on the track team. (singular)
The boys run on the track team. (plural)
If you are unsure what a plural verb looks like, know that many plural verbs end in s while the singular form of the verb does not - just like run/runs above. However, this is not true for the to be verbs.
Compound Subjects
Compound means two or more. The rule above is straightforward and easy to remember when you have one subject, but what happens when you have two or more subjects?
1. For singular compound subjects joined by and, use a plural verb.
2. For singular compound subjects joined by or or nor, use a singular verb.
3. For plural compound subjects joined by or or nor, use a plural verb.
4. For compound subjects that are both singular and plural joined by or ornor, use the verb that agrees with the closest subject.
