Lesson 3: Subject Verb Agreement

Verbs change depending on the subject you are writing about. The subject verb agreement occurs when the subject and verb endings agree in number and person. The subject of every sentence is either singular or plural and that determines the ending of the verb.

You can't have two "s" endings at the same time. You cannot write an "s" on the subject and an "s" on the verb. Many singular verbs have an "s" on the end; therefore, a plural subject can't have a singular verb.
Examples of Subject Verb Agreement
Singular Subject and Verb Plural Subject and Verb

That cloud does float high.

(one subject, cloud) (singular verb, does, with "s")

Those clouds do float high.

(more than one subject, clouds) (plural verb, do, without "s")

He uses a pen. We use pens.
Mom buys juice. Moms buy juice.
Dad loves his sport. Dads love their sports.
John drinks water. John and Fred drink water.

The verb and the subject must agree in the sentence. The action and the something or someone have to make sense. Singular subjects require singular verbs; plural subjects require plural verbs. In the sentences below the verbs agrees with each of the subject.

Singular Subject = Singular Verb

Example He reminds us to brush our teeth.
