41 Subject-Verb Agreement

Subject-verb agreement is one of the most common errors that people make. Having a solid understanding of this concept is critical when making a good impression, and it will help ensure that your ideas are communicated clearly.

Agreement

Agreement in speech and in writing refers to the proper grammatical match between words and phrases. Parts of sentences must agree, or correspond with other parts, in number, person, case, and gender.

Number. All parts must match in singular or plural forms.

Person. All parts must match in first person (I), second person (you), or third person (he, she, it, they) forms.

Case. All parts must match in subjective (I, you, he, she, it, they, we), objective (me, her, him, them, us), or possessive (my, mine, your, yours, his, her, hers, their, theirs, our, ours) forms.

Gender. All parts must match in male or female forms.

Subject-verb agreement describes the proper match between subjects and verbs.

Because subjects and verbs are either singular or plural, the subject of a sentence and the verb of a sentence must agree with each other in number. That is, a singular subject belongs with a singular verb form, and a plural subject belongs with a plural verb form.

Singular: The cat jumps over the fence.

Plural: The cats s over the fence.

Regular Verbs and Agreement

Regular verbs follow a predictable pattern. For example, in the third person singular, regular verbs always end in -s. Other forms of regular verbs do not end in -s. Study the following regular verb forms in the present tense.

Add an -es to the third person singular form of regular verbs that end in –sh, –x, –ch, and

–s. (I wish/He wishes, I fix/She fixes, I watch/It watches, I kiss/He kisses.)

Singular: I read every day.

Plural: We read every day.

In these sentences, the verb form stays the same for the first person singular and the first person plural.

Singular: You stretch before you go to bed.

Plural: You stretch before every game.

In these sentences, the verb form stays the same for the second person singular and the second person plural. In the singular form, the pronoun you refers to one person. In the plural form, the pronoun you refers to a group of people, such as a team.

Singular: My mother walks to work every morning.

In this sentence, the subject is mother. Because the sentence only refers to one mother, the subject is singular. If you replaced the word “mother” with a pronoun, it would be “she” which would take the third person singular form. Therefore, the verb in this sentence must be in the third person singular form.

Plural: My friends like he same music as I do.

In this sentence, the subject is friends. Because this subject refers to more than one person, the subject is plural. The verb in this sentence must be in the third person plural form.

Many singular subjects can be made plural by adding an -s. Most regular verbs in the present tense end with an -s in the third person singular. This does not make the verbs plural.

Singular subject, singular verb. The cat races across the yard.

Plural subject, plural verb. The cats race across the yard.

Exercise 1

Verbs: Be, Have, and Do

Exercise 2

Errors in Subject-Verb Agreement

Errors in subject-verb agreement may occur when

• a sentence contains a compound subject;
• the subject of the sentence is separate from the verb;
• the subject of the sentence is an indefinite pronoun, such as anyone or everyone;
• the subject of the sentence is a collective noun, such as team or organization;
• the subject appears after the verb.

Recognizing the sources of common errors in subject-verb agreement will help you avoid these errors in your writing. This section covers the subject-verb agreement errors in more detail.

Compound Subjects

A compound subject is formed by two or more nouns and the coordinating conjunctions and, or, or nor. A compound subject can be made of singular subjects, plural subjects, or a combination of singular and plural subjects.

Compound subjects combined with and take a plural verb form.

Two singular subjects: Alicia and Miguel ride their bikes to the beach.

Two plural subjects: The girls and the boys ride their bikes to the beach.

Singular and plural subjects: Alicia and the boys ride their bikes to the beach.

Compound subjects combined with or and nor are treated separately. The verb must agree with the subject that is nearest to the verb.

Two singular subjects: Neither Elizabeth nor Rianna wants to eat at that restaurant.

Two plural subjects: Neither the kids nor the adults want to eat at that restaurant.

Singular and plural subjects: Neither Elizabeth nor the kids want to eat at that restaurant.

Plural and singular subjects: Neither the kids not Elizabeth wants to eat at that restaurant.

Two singular subjects: Either you or Jason takes the furniture out of the garage.

Two plural subjects: Either you or the twins take the furniture out of the garage.

Singular and plural subjects: Either Jason or the twins take the furniture out of the garage.

Plural and singular subjects: Either the twins or Jason takes the furniture out of the garage.

Tip

If you can substitute the word they for the compound subject, then the sentence takes the third person plural verb form.

Separation of Subjects and Verbs

As you read or write, you may come across a sentence that contains a phrase or clause that separates the subject from the verb. Often, prepositional phrases or dependent clauses add more information to the sentence and appear between the subject and the verb. However, the subject and the verb must still agree.

Tip

If you have trouble finding the subject and verb, cross out or ignore the phrases and clauses that begin with prepositions or dependent words. The subject of a sentence will never be in a prepositional phrase or dependent clause.

The following is an example of a subject and verb separated by a prepositional phrase:

The following is an example of a subject and verb separated by a dependent clause:

Indefinite Pronouns

Indefinite pronouns refer to an unspecified person, thing, or number. When an indefinite pronoun serves as the subject of a sentence, you will often use a singular verb form.

To determine whether to use a singular or plural verb with an indefinite pronoun, consider the noun that the pronoun would refer to. If the noun is plural, then use a plural verb with the indefinite pronoun. View the chart to see a list of common indefinite pronouns and the verb forms they agree with.

Singular: Everybody in the kitchen sings along when that song comes on the radio.

The indefinite pronoun everybody takes a singular verb form because everybody refers to a group performing the same action as a single unit.

Plural: All the people in the kitchen sing along when that song comes on the radio.

The indefinite pronoun all takes a plural verb form because all refers to the plural noun

people. Because people is plural, all is plural.

Singular: All the cake is on the floor.

In this sentence, the indefinite pronoun all takes a singular verb form because all refers to the singular noun cake. Because cake is singular, all is singular.

Collective Nouns

A collective noun is a noun that identifies more than one person, place, or thing and considers those people, places, or things one singular unit. Because collective nouns are counted as one, they are singular and require a singular verb. Some commonly used collective nouns are group, team, army, flock, family, and class.

Singular: The class is going on a field trip.

In this sentence, class is a collective noun. Although the class consists of many students, the class is treated as a singular unit and requires a singular verb form.

The Subject Follows the Verb

You may encounter sentences in which the subject comes after the verb instead of before the verb. In other words, the subject of the sentence may not appear where you expect it to appear. To ensure proper subject-verb agreement, you must correctly identify the subject and the verb.

Here or There

In sentences that begin with here or there, the subject follows the verb.

If you have trouble identifying the subject and the verb in sentences that start with here

or there; it may help to reverse the order of the sentence so the subject comes first.

Questions

When you ask questions, a question word (who, what, where, when, why, or how) appears first. The verb and then the subject follow.

Whom are the people you are related to?

When am I going to go to the grocery store?

Tip

If you have trouble finding the subject and the verb in questions, try answering the question being asked.

When am I going to the grocery store? I am going to the grocery store tonight!
