Basic Principle: Singular subjects need
singular verbs; plural subjects need plural verbs.
My brother is
a nutritionist. My sisters are mathematicians.
The indefinite pronouns anyone,
everyone, someone, no one, nobody are always singular and, therefore,
require singular verbs.
Everyone has done his or her homework.
Somebody has left her purse.
Some indefinite pronouns — such as all,
some — are singular or plural depending on what they're referring to. (Is
the thing referred to countable or not?) Be careful choosing a verb to
accompany such pronouns.
Some of the beads are missing.
Some of the water is gone.
On the other hand, there is one indefinite
pronoun, none, that can be either singular or plural; it often doesn't
matter whether you use a singular or a plural verb — unless something else in
the sentence determines its number. (Writers generally think of none as
meaning not any and will choose a plural verb, as in "None of the
engines are working," but when something else makes us regard none
as meaning not one, we want a singular verb, as in "None of the
food is fresh.")
None of you claims responsibility for this incident?
None of you claim responsibility for this incident?
None of the students have done their homework.
In this last
example, the word their precludes the use of
the singular verb.
Some indefinite pronouns
are particularly troublesome. Everyone and everybody (listed
above, also) certainly feel like more than one person and, therefore,
students are sometimes tempted to use a plural verb with them. They are always
singular, though. Each is often followed by a prepositional phrase
ending in a plural word (Each of the cars), thus confusing the verb choice. Each,
too, is always singular and requires a singular verb.
finished his or her homework.
You would always say, "Everybody is
here." This means that the word is singular and nothing will change that.
of the students is responsible for doing his or her work in the library.
Don't let the word "students"
confuse you; the subject is each and each is always singular — Each is responsible.
Phrases such as together
with, as well as, and along with are not the same as and. The
phrase introduced by as well as or along with will modify the
earlier word (mayor in this case), but it does not compound the
subjects (as the word and would do).
The mayor as well as his brothers is going to prison.
The mayor and his brothers are going to jail.
The pronouns neither
and either are singular and require singular verbs even though they seem
to be referring, in a sense, to two things.
Neither of the two traffic lights is working.
Which shirt do you want for Christmas?
Either is fine with me.
In informal writing, neither and either
sometimes take a plural verb when these pronouns are followed by a
prepositional phrase beginning with of. This is particularly true of
interrogative constructions: "Have either of you two clowns read
the assignment?" "Are either of you taking this
seriously?" Burchfield calls this "a clash between notional and
The conjunction or
does not conjoin (as and does): when nor or or
is used the subject closer to the verb determines the number of the verb.
Whether the subject comes before or after the verb doesn't matter; the
proximity determines the number.
Either my father or my brothers are going to sell the house.
Neither my brothers nor my father is going to sell the house.
Are either my brothers or my father responsible?
Is either my father or my brothers responsible?
Because a sentence like "Neither my
brothers nor my father is going to sell the house" sounds peculiar,
it is probably a good idea to put the plural subject closer to the verb
whenever that is possible.
The words there
and here are never subjects.
There are two reasons [plural subject] for this.
There is no reason for this.
Here are two apples.
With these constructions (called expletive
constructions), the subject follows the verb but still determines the number of
Verbs in the present tense
for third-person, singular subjects (he, she, it and anything those
words can stand for) have s-endings. Other verbs do not add s-endings.
and she loves and they love_ and . . . .
Sometimes modifiers will
get between a subject and its verb, but these modifiers must not confuse the
agreement between the subject and its verb.
who has been convicted along with his four brothers on four counts of various
crimes but who also seems, like a cat, to have several political lives, is
finally going to jail.
Sometimes nouns take
weird forms and can fool us into thinking they're plural when they're really
singular and vice-versa. Words such as glasses, pants, pliers, and scissors are
regarded as plural (and require plural verbs) unless they're preceded the
phrase pair of (in which case the word pair becomes the subject).
My glasses were on the bed.
My pants were torn.
A pair of plaid trousers is in the closet.
Some words end in -s
and appear to be plural but are really singular and require singular verbs.
The news from the front is bad.
Measles is a dangerous disease for pregnant women.
On the other hand, some words ending in -s
refer to a single thing but are nonetheless plural and require a plural verb.
My assets were wiped out in the depression.
The average worker's earnings have gone up dramatically.
Our thanks go to the workers who supported the union.
The names of sports teams that do not end
in "s" will take a plural verb: the Miami Heat have been
looking … , The Connecticut Sun are hoping that new talent … .
such as half of, a part of, a percentage of, a majority of are sometimes
singular and sometimes plural, depending on the meaning. (The same is true, of
course, when all, any, more, most and some act as subjects.) Sums
and products of mathematical processes are expressed as singular and require
singular verbs. The expression "more than one" (oddly enough) takes a
singular verb: "More than one student has tried this."
Some of the voters are still angry.
A large percentage of the older population is voting against her.
Two-fifths of the troops were lost in the battle.
Two-fifths of the vineyard was destroyed by fire.
Forty percent of the students are in favour of changing the
Forty percent of the student body is in favour of changing the
Two and two is four.
Four times four divided by two is eight.
If your sentence
compounds a positive and a negative subject and one is plural, the other
singular, the verb should agree with the positive subject.
The department members but not the chair have
decided not to teach on Valentine's Day.
It is not the faculty members but the president who decides this
It was the speaker, not his ideas, that has provoked the
students to riot.
