Subject-verb agreement is the grammatical relationship in which a subject and its finite verb match in number and person. A singular subject takes a singular verb form, while a plural subject takes a plural form. In English, agreement is most visible in the present tense, especially with third-person singular verbs such as runs, does, and has.
Key Facts at a Glance
Subject-verb agreement matches a verb with the number and person of its subject.
A third-person singular present-tense verb usually ends in -s or -es.
Words between a subject and verb do not change the subject’s number.
In or and nor constructions, the verb usually agrees with the nearer subject.
Collective nouns can be singular or plural according to meaning and regional style.
Past-tense verbs usually show less agreement because worked and walked serve both numbers.
What Is Subject-Verb Agreement?
Subject-verb agreement means that the subject and the verb must correspond grammatically. Number is the main feature: The child plays uses a singular subject and singular verb, while The children play uses a plural subject and plural verb. Person also matters in forms of be, as shown by I am, you are, and she is.
Agreement applies to the finite verb, the verb that carries tense or modal information. In The researchers have completed the study, the auxiliary have agrees with researchers, while completed remains unchanged. In The researchers are completing the study, are carries agreement and completing does not.
Subject-verb agreement improves clarity because it identifies the grammatical relationship between an action and its performer. A mismatch can make formal writing sound careless, especially when a long phrase separates the subject from the verb.
Why Does Subject-Verb Agreement Matter?
Subject-verb agreement matters because readers use verb forms to interpret who or what performs an action. The rule is especially important in academic, professional, and edited writing, where errors can obscure meaning or reduce credibility.
Agreement is not a question of whether a sentence sounds conversationally familiar. Native speakers sometimes produce informal mismatches in speech, but edited prose normally follows a consistent grammatical pattern. The best correction preserves the intended meaning rather than mechanically changing the nearest noun.
How Do You Apply the Rule?
Use five steps: locate the complete subject, find the finite verb, remove distracting phrases, determine number and person, and select the matching verb. This method works for simple sentences and most complex constructions.
- Find the finite verb. In The list of changes was published, the finite verb is was.
- Ask who or what performs the action or receives the description. The answer is list.
- Remove interrupting material mentally. Of changes is a prepositional phrase, not part of the core subject.
- Determine number. List is singular.
- Check the verb. Was correctly matches list.
A useful editing test is to shorten the sentence temporarily: The list was published. If the shortened version is correct, restore the modifiers and check that the same subject-verb relationship remains.
What Is the Difference Between Singular and Plural Verb Forms?
Singular and plural verb forms differ most clearly in the present tense. A third-person singular subject generally takes a verb ending in -s or -es, while a plural subject takes the base form.
| Subject | Correct present verb | Example |
|---|---|---|
| The engine | starts | The engine starts quickly. |
| The engines | start | The engines start quickly. |
| A company | hires | A company hires specialists. |
| Several companies | hire | Several companies hire specialists. |
| She | does | She does the work. |
| They | do | They do the work. |
The pattern reverses a common learner expectation: singular nouns usually have no ending, but singular third-person present verbs often do. Thus, The dog runs is correct, while The dogs runs is incorrect.
The rule changes with be, have, and do. Their present forms are is/are, has/have, and does/do. Modal verbs such as can, should, and might take the same form with every subject: She can swim and They can swim.
How Do Compound Subjects Agree?
A compound subject joined by and usually takes a plural verb because it refers to two or more entities. The nurse and the patient are waiting contains two participants, so are is required.
A singular verb is possible when the joined words represent one combined idea, one dish, one title, or one unit. Fish and chips is popular in Britain treats the phrase as a dish. The intended meaning controls the choice.
| Compound subject | Verb | Reason |
|---|---|---|
| The manager and assistant | are | Two people |
| Bread and butter | is | One customary combination |
| Research and development | is | One organizational function |
| Tom and Maya | are | Two named individuals |
| Pride and Prejudice | is | One book title |
| Bacon and eggs | is | One meal, when treated as a dish |
When the meaning could be interpreted either way, rewrite the sentence. The manager and the assistant are responsible is clearer than relying on whether readers view the pair as one team or two individuals.
Which Noun Controls Agreement with Or and Nor?
With subjects joined by or, nor, either…or, or neither…nor, the verb usually agrees with the subject closest to it. Either the technician or the engineers are available takes are because engineers is nearer the verb.
| Construction | Nearer subject | Correct verb | Correct example |
|---|---|---|---|
| Either the interns or the supervisor | supervisor | is | Either the interns or the supervisor is attending. |
| Either the supervisor or the interns | interns | are | Either the supervisor or the interns are attending. |
| Neither the driver nor the passengers | passengers | are | Neither the driver nor the passengers are injured. |
| Neither the passengers nor the driver | driver | is | Neither the passengers nor the driver is injured. |
The proximity rule can produce an awkward sentence when the two subjects differ in number. In formal writing, place the plural subject last when possible, or rewrite the sentence: The supervisor or the interns are attending is acceptable, but The supervisor and the interns are not attending may express the intended meaning more directly.
Do Extra Phrases Change Subject-Verb Agreement?
Prepositional phrases, parenthetical expressions, and comparison phrases do not change the number of the main subject. The verb agrees with the head noun, not with a nearby object.
The box of chocolates is missing is correct because box is singular. Chocolates is the object of the preposition of, so it cannot control the verb.
| Distracting phrase | Core subject | Correct sentence |
|---|---|---|
| of old files | The folder | The folder of old files is locked. |
| along with two assistants | The director | The director, along with two assistants, is speaking. |
| as well as the interns | The researcher | The researcher, as well as the interns, has signed. |
| in addition to several errors | The report | The report, in addition to several errors, contains useful data. |
| accompanied by three guides | The visitor | The visitor, accompanied by three guides, was photographed. |
The same principle applies to relative clauses and parenthetical nouns. In The quality of the samples that were delivered has improved, has agrees with quality. The clause that were delivered describes samples, not quality.
How Can You Find the Real Subject?
Find the noun that the verb describes or that carries out the main action, then temporarily remove every phrase beginning with a preposition. In The results from the final experiment indicate a pattern, the core sentence is The results indicate a pattern.
Do not confuse an object with a subject. In The professor gave the students a test, professor controls gave; students and test receive something and do not control the verb.
Which Indefinite Pronouns Are Singular?
Pronouns such as each, either, neither, everyone, everybody, anyone, anybody, someone, somebody, no one, and nobody are grammatically singular and take singular verbs. Their meanings may refer to many people, but their grammatical structure treats people individually.
- Everyone wants a solution.
- Each of the files has a label.
- Neither of the proposals is affordable.
- Somebody knows the answer.
Pronouns such as both, few, many, several, and others are plural and take plural verbs.
- Both are ready.
- Several have arrived.
- Many were rejected.
The pronouns all, any, more, most, none, and some can be singular or plural. Their number depends on the noun they represent.
| Pronoun | Singular example | Plural example |
|---|---|---|
| Some | Some of the water is polluted. | Some of the bottles are empty. |
| All | All of the equipment is new. | All of the machines are new. |
| Most | Most of the work is complete. | Most of the tasks are complete. |
| None | None of the information is accurate. | None of the figures are accurate. |
Singular they does not make a singular antecedent plural. In Everyone has their badge, everyone still takes singular has, while singular they supplies a gender-neutral pronoun.
Are Collective Nouns Singular or Plural?
A collective noun takes a singular verb when the group acts as one unit and a plural verb when the sentence emphasizes separate members. Words such as team, family, committee, audience, staff, government, and class can therefore take either form.
- Unified action: The committee has approved the budget.
- Individual action: The committee are arguing among themselves.
American English generally prefers singular agreement for organizations and groups: The team is winning. British English more readily uses plural agreement when members act individually: The team are wearing their new shirts.
| Collective noun meaning | American English | British English tendency |
|---|---|---|
| Unit making one decision | The committee is voting. | The committee is voting. |
| Members disagreeing | The committee is divided. | The committee are divided. |
| Organization as entity | The company has announced results. | The company has announced results. |
| Players acting separately | The team is changing in the offseason. | The team are changing in the offseason. |
Choose one dialect and apply it consistently. For international business writing, singular agreement is usually the least distracting choice, particularly when an organization is treated as a legal or administrative entity.
How Do There and Here Sentences Work?
In sentences beginning with there or here, the grammatical subject usually follows the verb, so the following noun determines agreement. Write There is a problem for one problem and There are several problems for multiple problems.
- There is an error in the calculation.
- There are three errors in the calculation.
- Here is your receipt.
- Here are your receipts.
In speech, people sometimes use there’s before a plural noun, as in There’s two reasons. Edited writing normally uses there are two reasons. The contraction there’s is singular because it represents there is, not because the sentence has an unusual agreement system.
Writers should identify the delayed subject before choosing the verb. In There seem to be several explanations, explanations is plural, so seem is correct. In There seems to be one explanation, seems matches explanation.
Why Do Some Singular Nouns Look Plural?
Some nouns end in -s but represent a single subject, so they take singular verbs. Academic disciplines such as mathematics, physics, economics, and linguistics are normally singular when they name fields of study. Diseases such as measles and mumps are also singular.
- Mathematics is required for the course.
- Economics affects public policy.
- Physics explains the movement.
- Measles is highly contagious.
- The news is encouraging.
Other nouns are plural-only because they describe paired objects. Scissors, trousers, pants, shorts, glasses, binoculars, and shears take plural verbs when used alone.
| Noun | Usual agreement | Example |
|---|---|---|
| Mathematics | Singular | Mathematics is difficult for some students. |
| Economics | Singular | Economics is offered in the department. |
| News | Singular | The news was unexpected. |
| Scissors | Plural | The scissors are blunt. |
| Trousers | Plural | The trousers need cleaning. |
| A pair of scissors | Singular | A pair of scissors is on the desk. |
The noun after pair of does not control agreement. In Two pairs of trousers are missing, pairs is plural, so are is correct.
Does Agreement Change Across Tenses?
Subject-verb agreement remains active across tenses, but many English verb forms do not visibly distinguish singular from plural. Present-tense walks/walk shows the contrast clearly, whereas past-tense regular walked has one form for all subjects.
| Tense or structure | Singular example | Plural example |
|---|---|---|
| Present simple | The student writes. | The students write. |
| Past simple | The student wrote. | The students wrote. |
| Present perfect | The student has written. | The students have written. |
| Past perfect | The student had written. | The students had written. |
| Future with will | The student will write. | The students will write. |
| Present progressive | The student is writing. | The students are writing. |
The auxiliary verb carries agreement in multiword verb phrases. In The documents have been reviewed, have agrees with documents, while been and reviewed do not change.
Modal verbs do not change according to subject number. The device can operate and The devices can operate are both correct because can has one form.
Do Gerunds and Clauses Take Singular Verbs?
A gerund phrase or a that-clause used as the subject generally takes a singular verb because it represents one activity, fact, or proposition. Reading technical manuals requires patience treats the activity as one concept.
- What the witnesses reported was surprising.
- That the system failed remains unexplained.
- Checking every reference takes time.
- To compare the samples is difficult.
A plural verb can appear when the subject is genuinely plural: Reading and writing are separate skills. The conjunction joins two activities, so the compound subject takes are.
How Do Titles, Quantities, and Names Agree?
A title, sum, distance, period, or measurement can take a singular verb when it functions as one unit. The grammatical number depends on the meaning of the expression, not merely on the number printed inside it.
- Ten dollars is enough for lunch.
- Five years is a long commitment.
- Twenty kilometers is too far to walk.
- The Three Musketeers is a novel by Alexandre Dumas.
The verb becomes plural when the sentence focuses on separate units: Ten dollars were scattered across the floor. Here, the coins or notes are treated as individual objects rather than one sum.
| Expression | Meaning | Correct agreement |
|---|---|---|
| Ten dollars | One amount | Ten dollars is enough. |
| Ten dollar bills | Ten separate objects | Ten dollar bills are on the table. |
| Five years | One period | Five years is a long time. |
| Five years of records | Records as plural items | Five years of records are stored here. |
| The United States | One country | The United States is large. |
| The United States and Canada | Two countries | The United States and Canada are neighbors. |
How Do Relative Pronouns Affect Agreement?
A relative pronoun takes agreement from its antecedent in the relative clause. In She is one of the engineers who design the system, who refers to engineers, so design is plural.
The structure changes in She is the only engineer who designs the system. Here, who refers to the only engineer, so designs is singular.
- The machines that operate continuously require maintenance.
- The machine that operates continuously requires maintenance.
- I am the person who handles invoices.
- We are the people who handle invoices.
Do not let the noun nearest the relative verb mislead you. Identify what who, which, or that refers to, then match the verb with that antecedent.
What Are the Most Common Agreement Errors?
The most common errors arise when writers match a verb with a nearby noun instead of the actual subject. Long prepositional phrases, indefinite pronouns, collective nouns, and delayed subjects create most practical difficulties.
| Incorrect sentence | Correct sentence | Error source |
|---|---|---|
| The box of files are heavy. | The box of files is heavy. | Object of of mistaken for subject |
| Every employee have a key. | Every employee has a key. | Every treated as plural |
| The list of names were updated. | The list of names was updated. | Head noun ignored |
| There is several reasons. | There are several reasons. | Delayed plural subject |
| Neither the students nor the teacher are ready. | Neither the students nor the teacher is ready. | Nearest subject is singular |
| The news are encouraging. | The news is encouraging. | Singular mass noun misread |
An expert editing rule is to distrust proximity. The nearest noun is often an object, modifier, or noun inside a relative clause rather than the subject.
How Should You Fix a Difficult Agreement Sentence?
First identify the intended meaning, then rewrite the sentence if the formal rule produces an awkward result. A rewrite is often better than forcing a proximity construction or choosing between two distant nouns.
For example, change Either the manager or the assistants are responsible to The manager and the assistants share responsibility when both groups matter. Change The committee are divided to The committee members are divided when individual people, rather than the institution, are the focus.
Subject-verb agreement is not improved by changing every collective noun to plural. Agreement must reflect meaning, dialect, and the level of formality required by the audience.
Does British English Use Different Agreement Rules?
British English permits plural agreement with many collective nouns more often than American English, especially when the sentence emphasizes individual members. The underlying principle remains semantic: the verb reflects whether the group acts as one unit or as separate people.
| Context | American preference | British preference |
|---|---|---|
| Sports team as unit | The team is winning. | The team are winning. |
| Government as institution | The government has announced it. | The government has announced it. |
| Band members disagreeing | The band is arguing. | The band are arguing. |
| Staff acting individually | The staff is divided. | The staff are divided. |
Neither dialect makes all collective nouns permanently singular or permanently plural. Writers should follow the style guide for their publication. The Guardian and many British publishers allow plural collective agreement, while most American corporate style guides prefer singular forms.
How Should Writers Check Agreement?
A reliable subject-verb check takes less than a minute for most sentences. Read the sentence once for meaning, then perform a mechanical pass that ignores modifiers and tests the finite verb.
- Circle the finite verb.
- Underline the complete subject.
- Cross out phrases beginning with of, with, along with, as well as, and in addition to.
- Check whether the subject is singular, plural, a compound, or a collective noun.
- Verify special structures such as there is, either…or, relative clauses, and measurements.
- Read the sentence aloud once, then confirm the written rule rather than trusting sound alone.
For professional documents, search specifically for is/are, has/have, and does/do. These pairs account for many visible agreement errors. Automated grammar checkers can flag likely mismatches, but they may misread collective nouns, titles, and proximity constructions, so the writer must make the final decision.
Subject-Verb Agreement Rules: The Bottom Line
Subject-verb agreement matches a sentence’s finite verb with its subject in number and person. The core rules of subject verb agreement are simple: isolate the subject, ignore intervening phrases, identify singular or plural meaning, and select the corresponding verb. Compound subjects, indefinite pronouns, collective nouns, measurements, delayed subjects, and dialect choices require additional judgment.
The most dependable habit is to locate the head noun rather than the nearest noun. Once the real subject is identified, check special constructions such as or and nor, there is and there are, plural-only nouns, and relative clauses.
Frequently Asked Questions
Is “The team are winning” grammatically correct?
The team are winning is grammatical in varieties of British English when the sentence emphasizes individual team members. American English normally uses The team is winning because the team is treated as one unit. Choose the form that matches the intended meaning and the regional style of the publication.
Should “each of the students” take a singular verb?
Yes. Each of the students takes a singular verb because each is the head of the subject. Write Each of the students has a workbook, not Each of the students have a workbook. The plural noun students appears inside an of phrase and does not control agreement.
Is “none” singular or plural?
None can take either a singular or plural verb, depending on the noun it represents and the intended style. Write None of the water is clean for an uncountable singular mass noun, and None of the samples are clean for distinct plural items. Modern edited English accepts both patterns where meaning supports them.
Why is “mathematics is” correct?
Mathematics ends in -s, but it names one academic discipline, so it normally takes a singular verb: Mathematics is required. The same pattern applies to physics, economics, linguistics, and news. These nouns look plural but function grammatically as singular subjects.
Does singular “they” require a plural verb?
No. Singular they does not change the agreement of its antecedent. Write Everyone has their ticket, because everyone is singular and requires has. The pronoun their provides gender-neutral reference, while the verb still agrees with everyone.
Is “there’s two problems” acceptable?
There’s two problems is common in informal speech, but edited writing normally requires There are two problems. The delayed subject is two problems, which is plural. Use There is one problem when the following subject is singular and There are several problems when it is plural.
