Subject Verb Agreement: Rules, Examples, and Common Mistakes

Subject verb agreement means that the subject and verb in a sentence match in number. A singular subject takes a singular verb, while a plural subject takes a plural verb. The basic idea is simple, but real sentences often place extra words between the subject and verb. Pronouns, quantities, compound subjects, and unusual word order can also make the correct choice less obvious.

Accurate agreement makes English easier to understand in conversation, presentations, emails, and academic work. This guide explains the patterns that cause the most mistakes and gives you practical tests for checking your own sentences. If you want a wider overview first, read English Grammar Rules: The Complete Guide.

The Basic Subject Verb Agreement Rule

In the present simple, a singular third-person subject usually takes a verb ending in "-s" or "-es." Most plural subjects use the base form of the verb.

• "The student studies every evening."
• "The students study every evening."
• "She watches English videos."
• "They watch English videos."

The verb "be" has special forms:

• "I am ready."
• "He is ready."
• "We are ready."

The verbs "have" and "do" also change:

• "She has a question."
• "They have questions."
• "He does the assignment."
• "They do the assignment."

Notice that English spelling can feel backward to learners: a singular noun often has no "-s," but a singular present-tense verb often has one. Say the complete subject and verb together when you practice: "the student studies" and "the students study."

Find the Real Subject

The noun closest to the verb is not always the subject. A prepositional phrase beginning with words such as "of," "in," "with," or "between" may separate the real subject from its verb.

• "The list of vocabulary words is on the desk."
• "The students in the evening class are preparing for a presentation."
• "A box of old books was donated."
• "The effects of regular practice are easy to notice."

In the first sentence, "list" is singular. The plural noun "words" belongs to the phrase "of vocabulary words" and does not control the verb. In the second sentence, "students" is the plural subject, while "class" is only part of the phrase that describes the students.

Use the removal test when a sentence feels confusing. Temporarily remove the words between the possible subject and verb:

• "The list is on the desk."
• "The students are preparing."

This test also helps you see how English nouns function inside longer phrases.

Agreement with Compound Subjects

Two subjects joined by "and" normally take a plural verb.

• "Reading and speaking are important skills."
• "My teacher and my classmate help me practice."
• "The notebook and the dictionary belong to Sofia."

However, two words may describe one person, one item, or one combined idea. In that case, a singular verb may be correct.

• "Macaroni and cheese is my favorite lunch."
• "The writer and director is answering questions."

The second sentence refers to one person who is both the writer and the director. If two different people are involved, use "are": "The writer and the director are answering questions."

With "or," "nor," "either...or," and "neither...nor," the verb normally agrees with the subject closest to it.

• "Either the teacher or the students are presenting today."
• "Either the students or the teacher is presenting today."
• "Neither the keys nor the phone is in my bag."

If the sentence sounds awkward, rewrite it. For example, "Either the teacher is presenting today, or the students are" is clear and natural.

Agreement with Indefinite Pronouns

Indefinite pronouns do not name a specific person or thing. Many common indefinite pronouns are grammatically singular even when their meaning includes several people.

Use a singular verb with "everyone," "everybody," "someone," "somebody," "anyone," "anybody," "no one," "nobody," "each," "either," and "neither."

• "Everyone needs time to practice."
• "Each of the students has a notebook."
• "Neither of the answers is correct."
• "Someone in the offices knows the password."

The words "both," "few," "many," and "several" are plural.

• "Both are possible."
• "Several have asked the same question."
• "Many students make this mistake."

"All," "any," "more," "most," "none," and "some" can be singular or plural. Look at the noun that follows "of."

• "Some of the water is cold."
• "Some of the bottles are empty."
• "Most of the work is finished."
• "Most of the assignments are finished."

Quantities, Fractions, and Measurements

Expressions of time, money, distance, and weight often take a singular verb when the speaker treats the amount as one total.

• "Ten dollars is enough for lunch."
• "Three hours is a long time to wait."
• "Five miles is too far to walk today."

When the speaker focuses on individual units, a plural verb can be logical: "Ten dollars were scattered across the floor." Here, the sentence describes separate dollar bills or coins rather than one amount.

Fractions and percentages agree with the noun after "of."

• "Half of the cake is gone."
• "Half of the cookies are gone."
• "Twenty percent of the class is absent."
• "Twenty percent of the students are absent."

These patterns are easier when you identify whether the noun represents one mass, one group, or several countable items.

"There Is," "There Are," and Inverted Sentences

In sentences beginning with "there," the word "there" is not the true subject. The subject comes after the verb.

• "There is a notebook on the table."
• "There are three notebooks on the table."
• "There has been a change in the schedule."
• "There have been several changes in the schedule."

Casual speakers often use "there's" before a plural noun, as in "There's two seats available." You may hear this pattern, but standard writing prefers "There are two seats available."

Questions can also place the subject after part of the verb:

• "Where are the keys?"
• "Does your class meet on Friday?"
• "Have the results arrived?"

Turn the question into a statement if you need help finding the subject: "The keys are where?" or "Your class does meet on Friday."

Collective Nouns and Titles

Collective nouns name groups, including "class," "team," "family," "committee," and "company." In American English, a collective noun usually takes a singular verb when the group acts as one unit.

• "The class meets at 9:00."
• "The team is ready for the presentation."
• "The committee has reached a decision."

Use a plural noun when you want to emphasize individual members:

• "The students in the class have different goals."
• "The team members are putting on their uniforms."

Titles of books, films, courses, and other works take singular verbs, even when a title looks plural.

• "Great Expectations is a famous novel."
• "English Grammar Basics is offered this term."

The same principle applies to a word or phrase discussed as a single language item: "'Needs' is the correct verb in this sentence."

Make Agreement Automatic Through Meaningful Practice

Knowing a rule and using it quickly are different skills. In conversation, you cannot stop for a long grammar analysis before every verb. Effective practice should move from controlled choices to complete, personal sentences.

Columbia West College (CWC) connects grammar, speaking, and reading and writing through an integrated curriculum. Students can meet a grammar pattern in one class and then use the same target English in communication. English Speaking Success (ESS) also provides an 80-minute speaking class each day, offering 6 times more speaking practice than a typical listening and speaking class. This repeated output helps patterns such as "she works" and "they work" become easier to retrieve.

Try this four-step routine:

1. Underline the complete subject.
2. Cross out interrupting phrases.
3. Decide whether the subject is singular or plural.
4. Read the corrected sentence aloud twice.

Then make the sentence personal. Change "The student studies at night" to "My roommate studies at night" or "My friends study at night." Personal examples require you to think about meaning, not only memorize an answer.

Common Subject Verb Agreement Mistakes

Missing the third-person "-s."

Incorrect: "He study English after work."

Correct: "He studies English after work."

Agreeing with a nearby noun.

Incorrect: "The box of books are heavy."

Correct: "The box of books is heavy."

Treating "each" as plural.

Incorrect: "Each of the lessons have a quiz."

Correct: "Each of the lessons has a quiz."

Using a singular verb with a plural relative pronoun.

Incorrect: "She is one of the students who works on weekends."

Correct: "She is one of the students who work on weekends."

The relative pronoun "who" refers to "students," so "work" is plural. Compare: "She is the only student who works on weekends." Here, "who" refers to the singular noun phrase "the only student."

Forgetting agreement in long sentences.

Incorrect: "The main reason for the changes in our schedules are unclear."

Correct: "The main reason for the changes in our schedules is unclear."

When editing, check agreement separately from spelling and punctuation. One focused pass catches more errors than trying to inspect everything at once. The exercises in this English grammar test can help you practice after reviewing the rules.

Practice: Choose the Correct Verb

Choose the correct verb, then check the answers below.

1. "Every student (need / needs) a clear goal."
2. "The pages in this book (is / are) useful."
3. "Neither the teacher nor the students (was / were) late."
4. "Ten minutes (is / are) enough for this activity."
5. "Some of the information (seem / seems) outdated."
6. "There (is / are) two reasons for the change."
7. "My brother and sister (live / lives) in California."
8. "The title of those articles (sound / sounds) interesting."

Answers: 1. "needs"; 2. "are"; 3. "were"; 4. "is"; 5. "seems"; 6. "are"; 7. "live"; 8. "sounds."

Explain each answer to yourself. A short explanation such as "'Every' makes the subject singular" strengthens the rule. For more work with sentence parts, review Pronouns in English.

FAQ

What is subject verb agreement?

Subject verb agreement means that the verb matches its subject in number. A singular subject takes a singular verb, and a plural subject takes a plural verb.

Is "everyone is" or "everyone are" correct?

"Everyone is" is correct in standard English. "Everyone" has a plural idea, but it is grammatically singular.

Which verb agrees with "a number of"?

"A number of students are absent" uses a plural verb because the phrase means several students. "The number of students is increasing" uses a singular verb because "the number" is the subject.

How can I check agreement quickly?

Find the main subject, temporarily remove extra phrases, and decide whether the subject is singular or plural. Then read the subject and verb together.
