GRAMMAR AND MECHANICS
The Verb System: Subject-Verb Agreement
Subject-verb agreement refers to a change in the form of a
verb depending on its subject. The subject of a verb may be
singular or plural and it may be first-person (I, we) second-person
(you [singular], you [plural]), or third-person (he/she/it, they).
In English a verb changes form only when its subject is third-
person singular (he/she/it) and only in the present tense. The
following chart illustrates this rule:
Present Past
singular plural singular plural
I walk We walk I walked We walked
You walk You walk You walked You walked
He/she walks They walk He/She walked They walked
It walks It walked
The rule for subject-verb agreement is that in the present
tense, a verb with a third-person singular subject must always end
in -s. As you can see, the past tense form is the same regardless
of its subject.
A third-person singular subject is any person or thing that
can be replaced with one of the pronouns he, she, or it.
Nancy Colon [she] is going to lead a march on the
White House. The rest of the group [it] will follow
her. The rally [it] is scheduled for 1:15 PM. Some
marchers [they] may arrive early. They should wait for
the rest of the group before raising their placards. In
fact, no one [he/she] should raise a placard, sign, or
banner until the entire group [it] is assembled on the lawn.
SPECIAL PROBLEMS IN SUBJECT-VERB AGREEMENT
There are several sentence constructions that may make it
difficult for you to determine whether the main verb should have an
-s ending.
1. When Words Separate the Subject from Its Verb
Words that come between a subject and its verb do not affect
the number (singular or plural) of the subject. You must determine
which word is the sentence's subject and then use it to decide
whether the verb needs an -s ending.
The color of the stage setting seems drab.
The colors of the stage setting seem drab.
A computer with a variety of memory chips serves a special
purpose.
Computers with a variety of memory chips serve a special
purpose.
Sometimes words that come between a subject and its verb may
contain a complete clause with a subject and verb of its own. Most
often this will be a relative clause, beginning with who, which,
that or, less often, where or when. This can be confusing because
it's hard to tell which verb goes with which subject. Remember, a
subject and verb need only agree when they are in the same clause.
A woman who has a career and a family has very little time
for herself.
Relative pronouns may be either singular or plural, depending
on what noun they refer to. Therefore the verb of a relative
clause must agree with the noun that it is referring to.
A woman who has a career can still be a good mother.
Women who have careers sometimes wait to have children.
Be particularly careful editing subject-verb agreement when
the words that separate a singular subject from its verb sound like
they are making the subject plural. These words include expressions
such as in addition to, as well as, including, and together with.
These expressions do not function like the word and. In other
words, they do not make the subject plural even though they sound
like they do.
A microcomputer, as well as a mainframe, uses silicon chips.
A microcomputer and a mainframe use silicon chips.
The processing unit, together with all of its types of memory,
forms the heart of the machine.
The processing unit and the various types of memory form the
heart of the machine.
The memory, including the ROM and RAM, performs the computer's
operations.
The memory unit and the ROM and RAM perform the computer's
operations.
2. When the Subject Comes after Its Verb
In some sentences, you may reverse the order of a subject and
its verb in order to achieve an interesting effect. In other
sentences, you may want to begin with the words There or Here.
These sentence openers move the true subject to a position after
its verb. When you are editing your verbs, make sure that you check
these sentences very carefully to find the subject and to determine
the correct form of the verb.
At the end of the list is the divorced man.
At the end of the list are divorced men.
There is one significant reason why men remarry.
There are many reasons why men remarry.
However, remember that when you write a sentence that begins
with the word it you must always use the singular form of the main
verb (which usually ends in -s).
It seems that women have the greatest difficulty remarrying.
It does not mean that men do not have any problems.
It appears that men have a greater tendency to avoid
commitment than do women.
3. When Two or More Subjects are Joined by Or or Nor
When two or more subjects in a sentence are joined by or or
nor, the verb form is usually determined by the subject that is
closest to the verb.
Neither that woman nor her friends are unfulfilled.
Neither those women nor this one is unfulfilled.
It is true that a career or children affect a woman's
marriageability.
It is true that children or a career affects a woman's
marriageability.
4. When the Subject is a Singular Pronoun
When used as a subject, the following pronouns are always
considered singular and need verbs with -s endings on them in the
present tense: each, either, neither, every, everybody, everyone,
everything, anybody, anyone, anything, somebody, someone,
something, nobody, no one, nothing.
Everything contributes to the problem.
Someone who was abused as a child is likely to victimize his
or her own children.
Nobody who deals with the problem has all of the answers.
In terms of subject-verb agreement, the most troublesome
pronouns on the list above are everybody, everyone, either,
neither, every, and each. Everybody and everyone sound like groups
but grammatically they behave like singular subjects.
Everybody has to be concerned about family violence.
Everyone who deals with families sees these problems.
Either, neither, each, and every are always singular subjects
unless they are used with or or nor.
Neither is going to explode soon.
Either his sister or his parents are going to explode soon.
Each family member has control over his/her aggression.
5. When Words Separate a Singular Pronoun Subject from Its Verb
When a singular pronoun, such as either, neither, each, or
every is separated from its verb by other words, it is easy to get
confused about the form of the verb. Remember that words that come
between a subject and its verb do not affect the number of the
subject or the form of the verb.
Either of the parents is going to explode soon.
Neither parent is in control.
Each of the family members has to control his or her
aggression.
Each and every cause subject-verb agreement confusion when
they are separated from their verbs by the phrase of them or by two
nouns joined by and.
Each of them seems to be prone to violence.
Each of their parents has a repressed personality.
Every father and mother has to be careful.
The pronouns some, none, any, and most can be either singular
or plural subjects depending upon the words that follow them. For
example, some can mean "more than one," in which case the subject
is plural, or it can mean "a part of one," in which case the
subject is singular.
Some of the families studied commit emotional abuse.
Some of the problem is caused by television.
Most of the family members remain silent about it.
Most of the information comes from their neighbors.
6. When the Subject is a Collective Noun
A collective noun is the name of a group that usually
functions like a single unit. Some examples include family, class,
audience, crowd, committee, team, jury, orchestra and group. If you
are referring to the group as a single unit, then the noun is a
singular subject (and needs an -s ending on its verb). If you are
referring to the individual members of the group, then the noun is
a plural subject.
The team of scientists monitors the Milky Way.
The team of scientists disagree about those stars.
This group of stars is known as the Andromeda Galaxy.
That group of stars have separated to form new galaxies.
There is one collective noun that does function like the
others listed above: the word number. When it is used in the phrase
the number of, it is always a singular subject, and when it is used
in the phrase a number of, it is always a plural subject.
A number of galaxies are shaped like disks.
The number of disk-shaped galaxies is growing.
7. When the Subject is a Quantity
Like collective nouns, words that state a quantity or an
amount usually function like singular subjects, but they can
function like plural subjects when they refer to a part of
something, not the whole thing. Usually in this case, the quantity
is followed by the word of. Words of quantity include amounts of
time, money, height, length, width, space, and weight.
One hundred thousand light years is an extremely long time.
Three million dollars is the cost of the typical telescope.
Two-thirds of the galaxies are elliptical in shape.
8. When the Subject Looks Plural But is Singular in
Meaning
There are many subjects that look plural (in other words, that
end in -s) but are singular in meaning. These include the names of
school subjects--mathematics, linguistics, physics, economics,
civics--and the names of some diseases--measles, mumps, AIDS, and
herpes. They also include miscellaneous words like politics and
news.
Physics is the study of vector and scalar quantities.
Herpes is now impossible to cure.
The news about spiral galaxies seems unbelievable.
Mumps makes one's cheeks hurt and causes swelling and fever.
9. When the Subject is a Title
Even when a title is plural (like The New York Times), it
functions like a singular subject, and it needs an -s ending on its
verb.
The Hales Observatories tracks comets and meteors.
Principles of Astronomy explains the rotations of that galaxy.
One Hundred Thousand Galaxies provides fascinating
explanations about the content of the universe.
10. When the Subject is a Verbal Phrase
Sometimes an -ing or to + infinitive verb form is used as a
noun. A phrase containing one of these forms may appear as the
subject of a sentence. In these cases, the subject is always
singular.
Learning how to do something well takes practice and
determination.
To see is to believe.
