Transcript of Subject-Verb Agreement
- Mignon Fogarty (a.k.a. Grammar Girl)
What are subjects and verbs?
tells you who or what a sentence is about.
tells you what the subject is doing.
Generally, a sentence needs a subject
a verb in order to be complete.
Now look at this one:
The weatherperson predicted rain.
The subject of this sentence is 'the weatherperson' because it is performing the action of predicting rain.
Verbs are the words that indicate the action of the subject.
I walked to the store.
of this sentence is
because that is the action being performed.
Subjects at a glance
In a sentence, the subject is usually the person, place or thing that is doing something or being something.
Take a look at the following example:
I live in Barry.
of the sentence is
because it is performing the action of living in Barry.

How about this one?
My father is old.
This one is a bit trickier because it is not immediately clear what the subject (my father) is actually doing. Here, the
is the word
. The word 'is' implies a state of being, and 'to be' is an action; therefore, 'is' can function as a verb.
Singular or Plural?
Here are some singular subject-verb combinations:
*Note: The present tense verb for 'I' and 'you' is never 'is'; the present verb for 'I' is 'am'; the present verb for you is 'are'.
And here are some plural equivalents:
An important thing to remember is that subjects and verbs can come in
So, just what is subject-verb agreement?
A sentence's subject must agree with its verb. If it does not, then the sentence is not grammatically correct. Here are two key rules to remember:
1.) A singular subject must agree with a singular verb
2.) A plural subject must agree with a plural verb
Have a look at these examples:
My friend and I are going to the cinema tonight.
In this sentence there are
Therefore, the subject is
and needs a
But what if the sentence read like this...?
My friend and I
going to the cinema tonight.
The sentence would then be lacking subject-verb agreement because a
would have been partnered with a
Let's try another one!
Have a look at this one:
One of the boxes
In this sentence, it is tempting to think that the verb should be plural and that the sentence should read:
One of the boxes
However, the subject is
in this case because it is
of the boxes that is being opened. Therefore the verb must be
Time to take it up a notch!
This one is a bit more difficult. Can you spot the subject in this sentence?
"Located along the northern coast of the Bristol Channel, Barry is a seaside resort."
The subject in this sentence is "Barry".
The thing to remember is that the subject is not always the first word in the sentence. In the above example, all of the words before the comma (,) are just additional information about the subject.
...Now find the verb in this one!
In the following sentence, the subject is "Barry". But what is the subject's verb?
"Barry, which has a population of 50, 000 people, is much smaller than London."
The verb is "is".
Don't be deceived by the added information between the subject and verb. Often, words enclosed between a set of commas are just added information about the subject.
But is subject-verb agreement really that important?
That depends on the context.
In informal speech, subject-verb agreement is often ignored.
For example, you might hear someone say, "They was saying on the news that it is going to rain."
Here, the subject "they" is plural and the verb "was" is singular. Therefore, the subject and verb don't agree.
But, in an informal conversation, subject-verb agreement is not always crucial.
But sometimes it really does matter...
In formal writing, subject-verb agreement is
important, especially in the context of applying for work.
For instance, what if your cover letter said: "I is interested in applying for the job advertised..."?
You can bet that your application would be ignored! In other words, follow subject-verb agreement in formal situations!

Things to remember #1
Just because a subject ends in 's' does not necessarily mean it is a plural. Look at the sentence below:
The news is on at six.
Although the subject (news) ends in 's', it is still singular and requires a singular verb.
Singular words are often mistaken for plurals.
There are many words that look like they are plural. However, they are singular.
Here are some common examples:
Everyone, everything, anyone, everybody, each
So, if you ever encounter one of these words, especially near the the start of a sentence, chances are that your subject is singular.
