Subject-Verb Agreement

Master the rules that make subjects and verbs work together. Learn basic agreement, tricky subjects, intervening phrases, and special cases to write flawless sentences every time.

What Is Subject-Verb Agreement?

Subject-verb agreement is one of the most fundamental rules in English grammar. It means that the subject of a sentence and its verb must match in number — a singular subject takes a singular verb, and a plural subject takes a plural verb.

Think of It Like a Dance Partner

Imagine the subject and verb are dance partners. A solo dancer (singular subject) needs a solo routine (singular verb). A group of dancers (plural subject) performs a group routine (plural verb). When the partners are mismatched, the dance looks awkward — just like a sentence with disagreement between subject and verb sounds wrong.

The core principle is simple:

Singular Subject → Singular Verb

  • The dog runs in the park.
  • She writes every morning.
  • My brother plays guitar.
  • The car needs fuel.

Plural Subject → Plural Verb

  • The dogs run in the park.
  • They write every morning.
  • My brothers play guitar.
  • The cars need fuel.

The Counterintuitive Twist

Here is something that confuses many learners: in English, adding -s to a noun makes it plural (dog → dogs), but adding -s to a present-tense verb makes it singular (run → runs). So "The dog runs" is correct because the singular noun pairs with the -s verb form, while "The dogs run" is correct because the plural noun pairs with the base verb form. This opposite pattern is important to internalize.

Basic Rules of Agreement

Mastering these foundational rules will help you get subject-verb agreement right in the vast majority of sentences.

Rule 1: Third Person Singular Gets -s / -es

In the present tense, when the subject is he, she, it, or any singular noun, add -s or -es to the base verb.

Subject Verb Form Example
I walk (base form) I walk to school.
You walk (base form) You walk quickly.
He / She / It walks (add -s) He walks to school.
We / They walk (base form) They walk together.

Rule 2: Adding -es for Certain Verb Endings

If the verb ends in -s, -sh, -ch, -x, or -z, add -es instead of just -s for third person singular.

  • pass → He passes the test.
  • wash → She washes the dishes.
  • watch → He watches TV every evening.
  • fix → She fixes computers.
  • buzz → The phone buzzes constantly.

Rule 3: Verbs Ending in Consonant + y

If a verb ends in a consonant followed by -y, change the y to i and add -es.

  • study → She studies every night.
  • carry → He carries a backpack.
  • fly → The bird flies south in winter.

But if a vowel comes before the -y, just add -s: play → plays, enjoy → enjoys.

Rule 4: Irregular Verbs — Be, Have, Do

These three common verbs have irregular forms in the present tense:

To Be

  • I am
  • You are
  • He/She/It is
  • We/They are

To Have

  • I have
  • You have
  • He/She/It has
  • We/They have

To Do

  • I do
  • You do
  • He/She/It does
  • We/They do

Memory Trick: "One S at a Time"

In a correct present-tense sentence, the -s appears on either the subject or the verb — but never on both at the same time. "The cat sits" (singular noun, -s on verb). "The cats sit" (plural noun, no -s on verb). Think of it as a game of hot potato — only one word gets the -s.

Quick Practice: Choose the Correct Verb

Select the right verb form for each sentence:

  1. The teacher (explain / explains) the lesson clearly.
  2. My parents (live / lives) in Chennai.
  3. Water (freeze / freezes) at zero degrees.
  4. The children (play / plays) outside after school.
  5. She (do / does) her homework every evening.
Click to reveal answers
  1. explains — "The teacher" is singular (he/she)
  2. live — "My parents" is plural (they)
  3. freezes — "Water" is singular (it)
  4. play — "The children" is plural (they)
  5. does — "She" is third person singular

Tricky Subjects

Some subjects make agreement difficult because it is not immediately obvious whether they are singular or plural. This section covers the three trickiest categories: collective nouns, indefinite pronouns, and compound subjects.

Collective Nouns

Collective nouns name a group of people or things: team, family, class, committee, audience, jury, government, staff, crowd. Whether they take a singular or plural verb depends on whether the group acts as one unit or as separate individuals.

As One Unit → Singular Verb

  • The team is winning the match.
  • The committee has reached a decision.
  • My family lives in Hyderabad.
  • The audience was silent.

As Individuals → Plural Verb

  • The team are arguing among themselves.
  • The committee have different opinions.
  • My family are scattered across the country.
  • The jury are still debating the evidence.

American vs. British English

In American English, collective nouns almost always take singular verbs: "The team is playing well." In British English, plural verbs are common when the group members act individually: "The team are wearing their new jerseys." For most exams and formal writing, treating collective nouns as singular is the safer choice.

Indefinite Pronouns

Indefinite pronouns refer to non-specific people or things. They fall into three categories:

Always Singular Always Plural Singular or Plural
everyone, everybody, everything
someone, somebody, something
anyone, anybody, anything
no one, nobody, nothing
each, every, either, neither		 both
few
many
several
others		 all
some
most
any
none

Examples with singular indefinite pronouns:

  • Everyone is welcome at the event.
  • Nobody knows the answer.
  • Each of the students has a textbook.
  • Neither is acceptable.

Examples with plural indefinite pronouns:

  • Many are called, but few are chosen.
  • Several have already left.
  • Both are correct answers.

Singular OR plural — these depend on what follows "of":

  • Some of the cake is left. (cake = uncountable → singular)
  • Some of the cookies are left. (cookies = countable plural → plural)
  • All of the water has evaporated. (water = uncountable → singular)
  • All of the students have passed. (students = countable plural → plural)

Memory Trick: The "-one, -body, -thing" Rule

Any pronoun ending in -one, -body, or -thing is always singular. Think: "everyone" literally has the word "one" in it — it means "every single one," so it takes a singular verb. The same logic applies to someone, anybody, nothing, and all the rest.

Compound Subjects

Compound subjects contain two or more nouns joined by a conjunction. The conjunction determines whether the verb is singular or plural.

Conjunction Rule Example
and Usually plural (two things combined) Tom and Jerry are friends.
and (one concept) Singular if the two nouns form a single idea Bread and butter is my breakfast.
or / nor Verb agrees with the nearer subject Either the teacher or the students are responsible.
or / nor Verb agrees with the nearer subject Either the students or the teacher is responsible.

Quick Practice: Tricky Subjects

Choose the correct verb:

  1. The jury (has / have) reached a unanimous verdict.
  2. Somebody (is / are) knocking at the door.
  3. Rice and curry (is / are) a popular meal.
  4. Few of the guests (has / have) arrived.
  5. Neither the manager nor the employees (was / were) aware of the change.
  6. Each of the flowers (bloom / blooms) in spring.
Click to reveal answers
  1. has — "Jury" acting as one unit with a unanimous verdict
  2. is — "Somebody" is always singular (-body ending)
  3. is — "Rice and curry" forms a single dish/concept
  4. have — "Few" is always plural
  5. were — With "neither...nor," verb agrees with nearer subject "employees" (plural)
  6. blooms — "Each" is always singular

Intervening Phrases

One of the most common causes of agreement errors is a phrase that comes between the subject and the verb. These intervening words can trick you into matching the verb with the wrong noun.

The "Ignore the Middle" Strategy

Think of the subject and verb as two friends trying to talk across a crowded room. The people in between (prepositional phrases, relative clauses, appositives) are just noise. The subject still has to agree with the verb, no matter how many words separate them. When in doubt, mentally cross out everything between the subject and the verb, then check agreement.

Prepositional Phrases After the Subject

Phrases beginning with of, with, along with, together with, as well as, in addition to, including, besides, except, accompanied by do NOT change the number of the subject.

Correct

  • The box of chocolates is heavy.
  • The leader of the workers has spoken.
  • A bouquet of roses was delivered.
  • The quality of the products has improved.
  • The teacher, along with her students, is attending the conference.

Incorrect

  • The box of chocolates are heavy.
  • The leader of the workers have spoken.
  • A bouquet of roses were delivered.
  • The quality of the products have improved.
  • The teacher, along with her students, are attending.

Key Distinction: "Along With" Is Not "And"

Phrases like along with, together with, as well as, in addition to, accompanied by do NOT create a compound subject the way "and" does. Compare:

  • The president as well as the ministers is attending. (singular — "as well as" is just an addition)
  • The president and the ministers are attending. (plural — "and" creates a compound subject)

Relative Clauses and Appositives

Clauses and appositives inserted between the subject and verb should also be mentally removed:

  • The woman who lives next door is a doctor. (subject = "woman," not "door")
  • The paintings, which were donated last year, are priceless. (subject = "paintings")
  • My neighbor, a retired colonel, walks every morning. (subject = "neighbor")

Quick Practice: Find the Real Subject

Cross out the intervening phrase mentally and choose the correct verb:

  1. The list of items (is / are) on the table.
  2. The players on the team (practises / practise) daily.
  3. The price of these books (has / have) increased.
  4. The woman with ten cats (live / lives) on our street.
  5. The results of the experiment (was / were) surprising.
Click to reveal answers
  1. is — subject is "list" (singular), not "items"
  2. practise — subject is "players" (plural), not "team"
  3. has — subject is "price" (singular), not "books"
  4. lives — subject is "woman" (singular), not "cats"
  5. were — subject is "results" (plural), not "experiment"

Special Cases

English has several sentence patterns where finding the true subject requires extra care. These special cases catch even native speakers off guard.

There Is / There Are

When a sentence begins with "there", the word "there" is NOT the subject. The real subject comes after the verb. The verb must agree with that real subject.

  • There is a book on the shelf. (subject = "a book" → singular)
  • There are three books on the shelf. (subject = "three books" → plural)
  • There was an accident on the highway. (subject = "an accident" → singular)
  • There were many people at the party. (subject = "many people" → plural)

Here Is / Here Are

The same rule applies to sentences beginning with "here":

  • Here is your ticket. (subject = "your ticket" → singular)
  • Here are the documents you requested. (subject = "the documents" → plural)

Inverted Sentences (Subject After the Verb)

In questions and certain sentence structures, the subject comes after the verb. You still need agreement:

  • Where is the remote? (subject = "the remote")
  • Where are my keys? (subject = "my keys")
  • On the wall hangs a portrait. (subject = "a portrait")
  • Around the corner are two shops. (subject = "two shops")

Neither...Nor and Either...Or

With these correlative conjunctions, the verb agrees with the subject closer to it (the proximity rule):

Nearer Subject Is Singular

  • Neither the students nor the teacher is happy.
  • Either the dogs or the cat has eaten the food.
  • Neither my friends nor my brother was available.

Nearer Subject Is Plural

  • Neither the teacher nor the students are happy.
  • Either the cat or the dogs have eaten the food.
  • Neither my brother nor my friends were available.

Memory Trick: "The Nearest Neighbor Wins"

With either/or and neither/nor, imagine the verb is shy and only looks at its nearest neighbor (the closer subject). Whatever that neighbor looks like — singular or plural — the verb copies it. Tip: for smoother-sounding sentences, place the plural subject second so the plural verb sounds more natural.

Nouns That Look Plural but Are Singular

These words end in -s but take singular verbs:

  • News: The news is shocking.
  • Mathematics: Mathematics is challenging.
  • Physics: Physics requires logical thinking.
  • Economics: Economics deals with markets.
  • Measles: Measles is a contagious disease.
  • The United States: The United States is a large country.

Nouns That Look Singular but Are Plural

These words always take plural verbs:

  • Scissors: The scissors are in the drawer.
  • Trousers: These trousers are too tight.
  • Glasses: My glasses are broken.
  • People: The people are protesting.
  • Police: The police have arrived.

Amounts, Time, and Distances as Singular

When a number refers to a single unit or lump sum, use a singular verb:

  • Ten dollars is not enough for lunch. (one amount of money)
  • Three hours is a long time to wait. (one period of time)
  • Five kilometers is too far to walk. (one distance)
  • Two-thirds of the pizza has been eaten. (one portion)

Quick Practice: Special Cases

Choose the correct verb:

  1. There (is / are) many reasons to celebrate.
  2. Here (come / comes) the bus.
  3. Neither the pilot nor the passengers (was / were) injured.
  4. The news about the elections (is / are) exciting.
  5. Fifty dollars (is / are) a reasonable price.
  6. The police (is / are) investigating the case.
Click to reveal answers
  1. are — real subject is "many reasons" (plural)
  2. comes — real subject is "the bus" (singular)
  3. were — nearer subject "passengers" is plural
  4. is — "news" is always singular despite the -s
  5. is — "fifty dollars" is a single amount
  6. are — "police" is always plural

Common Mistakes and How to Fix Them

Here are the most frequent subject-verb agreement errors, along with corrections and explanations.

Mistake 1: Ignoring the Real Subject

Incorrect

  • The bag of apples are on the counter.
  • The cause of the problems remain unknown.
  • One of my friends are coming.

Correct

  • The bag of apples is on the counter. (subject = bag)
  • The cause of the problems remains unknown. (subject = cause)
  • One of my friends is coming. (subject = one)

Mistake 2: Treating "Everyone/Nobody" as Plural

Incorrect

  • Everyone are invited to the party.
  • Nobody know the truth.
  • Each of the rooms have a window.

Correct

  • Everyone is invited to the party.
  • Nobody knows the truth.
  • Each of the rooms has a window.

Mistake 3: "There Is" with Plural Subjects

Incorrect

  • There is many students in the hall.
  • There is two options available.

Correct

  • There are many students in the hall.
  • There are two options available.

Mistake 4: Confusing "As Well As" with "And"

Incorrect

  • The captain, as well as the players, are ready.
  • The CEO, together with the board, have approved it.

Correct

  • The captain, as well as the players, is ready.
  • The CEO, together with the board, has approved it.

Mistake 5: Wrong Verb with Neither/Nor

Incorrect

  • Neither the boys nor the girl are going.
  • Either you or he are wrong.

Correct

  • Neither the boys nor the girl is going. (nearer = girl)
  • Either you or he is wrong. (nearer = he)

Quick Checklist for Error-Free Agreement

  • Step 1: Find the subject. Ask "Who or what is doing the action?"
  • Step 2: Cross out all prepositional phrases and interrupting clauses between the subject and verb.
  • Step 3: Determine if the subject is singular or plural.
  • Step 4: Match the verb. Singular subjects get -s/-es verbs; plural subjects get base-form verbs.
  • Step 5: Double-check special cases (there is/are, collective nouns, indefinite pronouns).
