Rules of Subject Verb Agreement
Rules of Subject Verb Agreement
Rules of Subject Verb Agreement
1. Two or more subjects joined by and are plural and take a plural verb
a. Example: Jan, John, and Bob walk to the store. Bob and his brothers walk to the store.
2. If a subject is modified by the words each or every, that subject is singular and will take a singular
verb
a. Example: Each boy and girl walks to the store.
3. If plural subjects are joined by or, nor, or but, the verb must only agree with the last subject named
a. Example: Either Bob or his brother walks to the store. Neither Bob nor his brothers walk to the store.
*Not Bob but his brothers walk to the store *Not Bob but his brother walks to the store
4. Indefinite pronouns are usually singular and take a singular verb form
indefinite pronouns:
anybody
everyone
neither
someone
anyone
everything
nobody
something
anything
one
no one
each
somebody
nothing
7. When a collective noun, such as family, group, committee, or class, is the subject, the verb will be singular
a. Example: My family with all my crazy cousins always walks to the store.
8. A few nouns, such as economics, mumps, measles, or news end in s but are considered singular. You can
tell these s words are singular because if you take the s away, you dont have a noun. For example,
economic and new are adjectives that describe a noun. Mump and measle just dont make any sense.
a. Example: Economics is her favorite subject.
9. When the subject is a unit of measurement of time, distance, money, weight, etc. The unit is considered
singular, and the verb will end in s.
1. Example: Ten pounds of chocolate is too much to eat at once.
2. Thirteen feet of kite string tangles very easily.
10. In a question or in a sentence that begins with there or here, the verb will often come before the subject.

Subject-Verb Agreement
A grammar help worksheet by Abbie Potter Henry
(Subjects are in bold typeface and verbs are underlined)
Subject-Verb Agreement means that subjects and verbs must always agree in number.
Not only does a verb change its form to tell time, but it also can change its form to indicate how
many subjects it has.
For example, take the verb run. When we are in the present tense, the verb run
changes form to show that its subject is singular when its subject is anything but I or you.
Study the following chart.
Singular Subjects
First Person:
I run.
Second Person:
You run.
Third Person:
Heruns. Sheruns. Theboy runs.
Plural Subjects
Werun.
You all run.
They run.
Did you notice that in the third person singular, an s was added to the verb form? The
fact is that all present tense verbs have an s added to them when the subject is third person
singular.
Think for a moment about the verbs, walk, run, eat, sleep, try, study, and work. Now,
give these verbs the subject I. I walk; I run; I eat; the pronoun I is the only word that can
be a first person subject; likewise, the word you is the only word that can be a second person
subject. The present tense verb for you remains the same as for I. You walk; you run; you eat.
However, when we change the subject I or you to he, or the cat, we must add an
s. to each verb. The cat walks; the cat runs; the cat eats; etc. This is a simple rule that most of
us automatically use without even thinking, and it applies to every singular third person verb in
the entire English language, from walk/walks to run/runs to laugh/laughs to cry/cries. This also
includes the helping verbs do/does, is/are, and has/have.
While we are not likely to write or speak the following sentences: I walks; They walks;
The cat walk, if we do, we create a Subject-Verb Agreement Error.
Subject-Verb Agreement Errors are very serious and signal that the writer does not
have mastery over the English Language. Thus, it is important that writers understand the
following thirteen different situations that might cause subject-verb agreement errors. Because
of these special situations, there are thirteen corresponding rules to ensure that our subjects and
verbs always agree in number.
