Subject-verb agreement means the subject and verb in a sentence must match.
A singular subject usually takes a singular verb. A plural subject usually takes a plural verb.
Correct:
- The dog runs fast.
- The dogs run fast.
This rule helps sentences sound clear, natural, and grammatically correct.
Quick Answer
Subject-verb agreement is the grammar rule that says a verb must agree with its subject in number and person.
Number means singular or plural.
Person means whether the subject is I, you, he, she, it, we, or they.
Basic examples:
| Subject | Verb | Example |
|---|---|---|
| Singular | Singular Verb | The cat sleeps. |
| Plural | Plural Verb | The cats sleep. |
| I | Special Form | I sleep. |
| You | Special Form | You sleep. |
The rule matters most in the present tense because many singular verbs add -s or -es.
The Rule Explained
The subject tells who or what the sentence is about. The verb tells what the subject does or what state it is in.
In the present tense, a third-person singular subject often uses a verb ending in -s or -es.
Examples:
- The student reads every night.
- The teacher explains the lesson.
- The phone buzzes on the desk.
Plural subjects usually use the base verb form.
Examples:
- The students read every night.
- The teachers explain the lesson.
- The phones buzz on the desk.
This pattern can feel backward because plural nouns often end in -s, but plural present-tense verbs usually do not.
Correct:
- The dog barks.
- The dogs bark.
The noun changes from dog to dogs. The verb changes from barks to bark.
When To Use It
Use subject-verb agreement in every complete sentence.
The easiest way to apply the rule is to find the real subject first. Then choose the verb that matches that subject.
Correct:
- The book belongs on the shelf.
The subject is book, not shelf. Since book is singular, the verb is belongs.
Correct:
- The books belong on the shelf.
The subject is books, so the verb is belong.
With Words Between The Subject And Verb
Do not let extra words between the subject and verb confuse you.
Correct:
- The box of markers is on the table.
The subject is box, not markers.
Correct:
- The boxes of markers are on the table.
The subject is boxes, not markers.
Prepositional phrases often create this problem. Common prepositions include of, in, on, with, near, beside, and between.
More examples:
- The list of names is on my desk.
- The files in the folder are missing.
- The teacher with two assistants is here.
- The chairs near the window need repair.
With Compound Subjects Joined By And
Two or more subjects joined by and usually take a plural verb.
Correct:
- Mia and Jordan are ready.
- My brother and sister live nearby.
- The laptop and charger are in my bag.
The sentence is talking about more than one person or thing.
Sometimes, two words joined by and refer to one combined idea. In that case, a singular verb can be correct.
Correct:
- Peanut butter and jelly is my favorite sandwich.
- Mac and cheese is on the menu.
The phrase names one dish or one combined item.
With Or And Nor
When subjects are joined by or or nor, the verb usually agrees with the subject closer to it.
Correct:
- Either the teacher or the students are presenting.
- Either the students or the teacher is presenting.
- Neither the manager nor the employees were available.
- Neither the employees nor the manager was available.
This is called the nearest-subject rule.
If the sentence sounds awkward, rewrite it.
Awkward:
- Either the report or the emails are missing.
Better:
- Either the emails are missing, or the report is missing.
With Each And Every
Words such as each and every usually point to one person or thing at a time. They take singular verbs.
Correct:
- Each student has a notebook.
- Every desk needs a label.
- Each of the forms is signed.
- Every one of the answers matters.
Even when the sentence mentions more than one person or thing, each and every focus on them individually.
With Indefinite Pronouns
Some indefinite pronouns are usually singular.
Singular indefinite pronouns include:
- anyone
- anybody
- everyone
- everybody
- someone
- somebody
- no one
- nobody
- each
- either
- neither
Correct:
- Everyone is ready.
- Somebody has my pen.
- Neither of the answers seems right.
- Each of the books belongs on this shelf.
Some indefinite pronouns can be singular or plural depending on what they refer to.
These include:
- all
- any
- more
- most
- none
- some
Correct:
- Some of the cake is gone.
- Some of the cookies are gone.
- Most of the work is finished.
- Most of the files are saved.
Look at the noun after of to understand the meaning.
With Collective Nouns
A collective noun names a group, such as team, family, class, committee, or group.
In American English, collective nouns usually take singular verbs when the group acts as one unit.
Correct:
- The team is practicing today.
- The committee has made its decision.
- My family lives in Texas.
Use a plural verb only when you clearly mean the members acting separately. In American English, this often sounds better when rewritten.
Less natural:
- The team are arguing about their roles.
Better:
- The team members are arguing about their roles.
With There Is And There Are
In sentences that begin with there is or there are, the word there is not the real subject.
Look after the verb to find the subject.
Correct:
- There is one email in my inbox.
- There are three emails in my inbox.
- There was a problem with the order.
- There were several problems with the order.
The verb agrees with the real subject: email, emails, problem, or problems.
With Questions
In questions, the subject may come after part of the verb.
Correct:
- Where is the file?
- Where are the files?
- Does your sister work here?
- Do your sisters work here?
To check agreement, turn the question into a statement.
Question:
- Does your sister work here?
Statement:
- Your sister does work here.
The subject is sister, so does is correct.
With Titles, Amounts, And Measurements
A title of a book, movie, show, or article usually takes a singular verb, even if it contains a plural word.
Correct:
- The Hunger Games is a popular novel.
- Friends is still widely watched.
Amounts of money, time, distance, and measurement often take singular verbs when they are treated as one total amount.
Correct:
- Ten dollars is enough for lunch.
- Five miles is too far to walk today.
- Three hours is a long wait.
If the items are treated separately, a plural verb may be clearer.
Correct:
- Ten one-dollar bills are on the counter.
With A Number Of And The Number Of
These two phrases look similar, but they use different verbs.
A number of means several, so it takes a plural verb.
Correct:
- A number of students are absent.
The number of refers to one total number, so it takes a singular verb.
Correct:
- The number of students is higher this year.
This is a common subject-verb agreement trap.
When Not To Use It
Do not match the verb to the nearest noun unless that noun is the real subject.
Incorrect:
- The list of supplies are on the desk.
Correct:
- The list of supplies is on the desk.
The subject is list, not supplies.
Do not treat a word as plural only because it ends in -s.
Correct:
- Mathematics is my favorite subject.
- The news is surprising.
- Physics requires careful study.
These words look plural, but they are treated as singular in these sentences.
Do not treat there as the subject.
Incorrect:
- There is many reasons to wait.
Correct:
- There are many reasons to wait.
The subject is reasons, so the verb is are.
Do not let a subject complement control the verb.
Incorrect:
- The main problem are the delays.
Correct:
- The main problem is the delays.
The subject is problem, so the verb is is.

Quick Memory Fix Or Rule Of Thumb
Use this rule:
Find The Real Subject First. Then Match The Verb To It.
Do not choose the verb by looking at the closest noun. The closest noun is not always the subject.
Ask:
- Who or what is the sentence about?
- Is that subject singular or plural?
- Are extra words hiding the real subject?
- Does the sentence begin with there or here?
- Are the subjects joined by and, or, or nor?
Once you find the real subject, the verb choice becomes much easier.
