Problems with Subject-
Verb Agreement
When Subjects and Verbs Don’t Match
What is subject-verb agreement?
In any sentence, the subject and the verb
must match—or agree—in number.
If the subject is singular (one person, place, or
thing), the verb must also be singular.
If the subject is plural (more than one), the verb
must also be plural.
Example
Singular: The skydiver jumps out of the airplane.
Plural: The skydivers jump out of the airplane.
Verb Endings
Regular verbs (with forms that follow standard English patterns) have two forms in the present tense: one that ends in –s and one that has no ending.
The third-person subjects he, she, it, and singular nouns always use the form that ends in –s.
First-person subjects (I), second-person subjects (you), and plural subjects use the form with no ending.
Verb Endings
Singular Plural
First person I walk. no –s We walk.
Second person You walk. no -s You walk.
Third person He (she, it) walks.
Joe walks.
The student walks.
all end
in –s
They walk.
Joe and Alice walk.
The students walk.

How can you find subject-verb
agreement errors?
Look for the five trouble spots that often signal
subject-verb agreement problems:
1. The verb is a form of be, have, or do.
2. Words come between the subject and the verb.
3. The sentence has a compound subject.
4. The subject is an indefinite pronoun.
5. The verb comes before the subject.
1. The verb is a form of be, have, or
do
The verbs be, have, and do do not follow the rules
for forming singular and plural verbs; they are
irregular verbs.
These verbs can cause problems for writers who in
conversation use the same form in all cases (He
do the cleaning; they do the cleaning).
People also sometimes use the word be instead of
the correct form of be (She be on vacation).
Forms of the verb be, present tense
Singular Plural
First person I am We are
Second person You are You are
Third person She, he, it is
The student is
They are
The students are
Forms of the verb be, past tense
Singular Plural
First person I was We were
Second person You were You were
Third person She, he, it was
The student was
They were
The students were
Forms of the verb have, present tense
Singular Plural
First person I have We have
Second person You have You have
Third person She, he, it has

Forms of the verb do, present tense

2. Words come between the subject
and the verb
When the subject and verb aren’t right next to
each other, it is more difficult to find them and
to make sure they agree.
Most often, either a prepositional phrase or a
dependent clause comes between the subject
and the verb.
Prepositional phrase between the
subject and the verb
A prepositional phrase starts with a preposition and ends with a noun or pronoun:
I took a nap on my bed and woke up after dinner.
The subject of a sentence is never in a prepositional phrase.
When you are looking for the subject of a sentence, you can cross out any prepositional phrases. This strategy should help you to find the real subject and decide whether it agrees with the verb.
Making subjects and verbs agree
when they are separated by a
prepositional phrase
Students on a tight schedule (know / knows)
they shouldn’t procrastinate.
First, underline the subject.
Cross out any prepositional phrases.
Ask: Is the subject singular or plural? Plural.
Choose the form of the verb that matches the
third person plural subject.
Students on a tight schedule (know / knows)
they shouldn’t procrastinate.
A) know
B) knows
Choose the form of the verb that matches the
third person plural subject.
Students on a tight schedule (know / knows)
they shouldn’t procrastinate.
ANSWER:
A) know
B) knows
Dependent clause between the
subject and the verb
A dependent clause has a subject and a verb, but it does not express a complete thought.
When a dependent clause comes between the subject and the verb, it usually starts with the word who, whose, whom, that, or which.
The subject of a sentence is never a dependent clause. When you are looking for the subject of a sentence, you can cross out any dependent clauses.
Making subjects and verbs agree
when they are separated by a
dependent clause
Dave, who is one of my brothers, (distract
/distracts) me whenever I try to study.
First, underline the subject.
Cross out any dependent clause.
Ask: Is the subject singular or plural? Singular.
Choose the form of the verb that matches the
third-person singular subject.
Dave, who is one of my brothers, (distract
/distracts) me whenever I try to study.
A) distract
B) distracts
Choose the form of the verb that matches the
third-person singular subject.
Dave, who is one of my brothers, (distract
/distracts) me whenever I try to study.
ANSWER:
A) distract
B) distracts
3. The sentence has a compound
subject
A compound subject is two (or more) subjects
joined by and, or, or nor.
If two subjects are joined by and, they combine to
become a plural subject, and the verb must be
plural too.
If two subjects are separated by the word or or nor,
they are not combined. The verb should agree
with whichever subject is closer to it.
Making subjects and verbs agree in a
sentence with a compound subject
Either Jocelyn or Dan (help / helps) me stay focused when I have a long paper to write.
First, underline the subjects.
Circle the word between the subjects.
Ask: Does that word join the subjects to make them plural or keep them separate? Keeps them separate.
Ask: Is the subject that is closer to the verb singular or plural? Singular.
Choose the verb form that agrees with the subject
that is closer to the verb.
Either Jocelyn or Dan (help / helps) me stay
focused when I have a long paper to write.
A) help
B) helps
Choose the verb form that agrees with the subject
that is closer to the verb.
Either Jocelyn or Dan (help / helps) me stay
focused when I have a long paper to write.
ANSWER:
A) help
B) helps
4. The subject is an indefinite
pronoun
An indefinite pronoun replaces a general person, place, or thing or a general group of people, places, or things.
Often, an indefinite pronoun is followed by a prepositional phrase or dependent clause. Remember that the verb of a sentence must agree with the subject of the sentence, and the subject of a sentence is never in a prepositional phrase or dependent clause.
Indefinite pronouns are often singular, though
there are some exceptions.
Always singular: another, anybody, anyone, anything,
each (of), either (of), everybody, everyone, everything,
much, neither (of), nobody, no one, nothing, one (of),
somebody, someone, something
May be singular or plural: all, any, none, some

pronoun

First, underline the subject.
Cross out any prepositional phrase or dependent clause that follows the subject.
Ask: Is the subject singular or plural? Singular.
Choose the verb form that agrees with the subject.

procrastinating by watching movies.
A) is
B) are

One of my worst habits (is / are)

5. The verb comes before the subject
In most sentences, the subject comes before the
verb. Two kinds of sentences often reverse the
usual subject-verb order: questions and
sentences that begin with here or there.
In these two types of sentences, you need to check
for errors in subject-verb agreement.
Questions
In questions, the verb or part of the verb comes
before the subject.
To find the subject and verb, you can turn the
question around as if you were going to answer
it.
Where is the theater? / The theater is…
Are you leaving? / You are leaving.
Sentences that begin with here or
there
When a sentence begins with here or there, the
subject often follows the verb.
Turn the sentence around to find the subject and
verb.
Here is your purse. / Your purse is here.
There are the car keys. / The car keys are there.
Making subjects and verbs agree
when the verb comes before the
subject
What movies (is / are) this theater showing?
If the sentence is a question, turn the question into
a statement. This theater (is / are) showing the movies.

Choose the form of the verb that matches the
subject.
