Subject-Verb Agreement: Rules & Tricky Cases Explained

Master the Art of Matching Subjects and Verbs

Reviewed by the Grammarlyzer Editorial Team · Our Review Standards · Published January 22, 2026 · Updated June 13, 2026

Quick Answer

The Rule: Subjects and verbs must agree in number—singular subjects take singular verbs, plural subjects take plural verbs.

Examples: "The dog runs" (singular) vs. "The dogs run" (plural).

Key Tip: Find the true subject and ignore words between the subject and verb.

Memory Trick: Singular subject, singular verb; plural subject, plural verb.

🔑 Key Takeaway

Match the verb to the true subject’s number, not to nearby words.

Singular vs. Plural: Common Cases at a Glance

Subject Type Correct Form Common Error
Simple singular The report is ready. The report are ready. ❌
Subject + of-phrase The list of errors is long. The list of errors are long. ❌ (errors is not the subject)
Compound with and The manager and the assistant are available. The manager and the assistant is available. ❌
Neither/nor — mixed number Neither the director nor the staff were notified. Neither the director nor the staff was notified. ❌ (nearest subject is plural)
Collective noun (AmE) The team is reviewing the proposal. The team are reviewing the proposal. ❌ (British English differs)

Agreement Decision Matrix

Subject-verb agreement starts with one question: what is the true subject? Do not choose the verb from the noun closest to it until you have found the head of the subject.

Sentence Pattern What Controls the Verb Example
Simple subject The main noun or pronoun The report is ready. The reports are ready.
Subject + prepositional phrase The noun before the preposition The list of errors is short.
Compound subject with and Usually plural The designer and writer are available.
Either/or or neither/nor The subject nearest the verb Neither the manager nor the employees were available.
There is / there are The real subject after the verb There are three issues in the draft.
Collective noun Whether the group acts as one unit or members The team is reviewing the proposal.

Eight Agreement Decisions Writers Make Most

Agreement errors are easy to miss because the sentence often sounds fluent. These decisions cover the patterns most likely to survive a quick read.

1. Find the head noun

The head noun is the core noun in the subject phrase. Ignore extra description when matching the verb.

Clear:

The folder of signed forms is on the server.

2. Ignore prepositional phrases

Phrases beginning with of, with, near, inside, or for can distract you from the real subject.

Incorrect:

The list of tasks are long.

Correct:

The list of tasks is long.

3. Treat and as plural

Most subjects joined by and take a plural verb because they name more than one person, object, or idea.

Clear:

The schedule and budget are attached.

4. Check nearest subject with or/nor

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

Clear:

Neither the director nor the reviewers are available today.

5. Look after there is / there are

There is not the subject. The real subject appears after the verb.

Incorrect:

There is three files missing.

Correct:

There are three files missing.

6. Handle collective nouns by meaning

In American English, a collective noun usually takes a singular verb when the group acts as one unit.

Clear:

The committee has approved the policy.

7. Watch indefinite pronouns

Words such as everyone, each, someone, and nobody usually take singular verbs.

Clear:

Everyone has submitted the form.

8. Do not let distance break agreement

Long subjects make agreement harder because the verb appears far away from the head noun. Shorten the subject mentally before choosing the verb.

Clear:

The explanation of the results and limitations is included in the appendix.

Common Mistakes

Matching the verb to the nearest noun

Incorrect:

The stack of invoices are on my desk.

Correct:

The stack of invoices is on my desk.

The subject is stack, not invoices. The prepositional phrase distracts from the true subject.

Using there is before a plural subject

Incorrect:

There is several questions about the launch plan.

Correct:

There are several questions about the launch plan.

The real subject is questions, which is plural.

Treating everyone as plural

Incorrect:

Everyone have access to the folder.

Correct:

Everyone has access to the folder.

Everyone refers to all people, but grammatically it is singular.

Forgetting the nearest-subject rule with neither/nor

Incorrect:

Neither the reviewers nor the manager are available.

Correct:

Neither the reviewers nor the manager is available.

The nearest subject is manager, so the verb is singular.

Changing style mid-document for collective nouns

Inconsistent:

The team is reviewing the proposal. The team are sending comments tomorrow.

Consistent:

The team is reviewing the proposal. The team is sending comments tomorrow.

In American English, treat the team as one unit unless you intentionally shift to individual members.

Frequently Asked Questions

What is subject-verb agreement?

Subject-verb agreement means the verb must match the number of the true subject: singular subjects take singular verbs, and plural subjects take plural verbs.

What is the fastest subject-verb agreement test?

Find the head noun of the subject, ignore interrupting phrases, then choose the verb form that matches that head noun.

Why do agreement errors happen near prepositional phrases?

A prepositional phrase can place a plural noun next to the verb, but the verb still agrees with the subject before the phrase.

How do either/or and neither/nor affect agreement?

With either/or and neither/nor, the verb usually agrees with the subject closest to the verb.

Are collective nouns singular or plural?

In American English, collective nouns such as team, committee, and staff are usually singular when the group acts as one unit.

Should I write there is or there are?

Look after there is or there are to find the real subject. Use there is for singular subjects and there are for plural subjects.

Can Grammarlyzer catch every agreement error?

Grammarlyzer can catch many simple agreement errors, but complex subjects, collective nouns, and style choices still need manual review.

Real-World Examples

📏 Basic:

The dog runs in the park. The dogs run in the park.

Singular subject = singular verb (-s). Plural subject = plural verb (no -s).
⚠️ Tricky:

The list of items is on the table.

'List' is the subject (singular), not 'items' — don't be fooled by the prepositional phrase
⚠️ Compound:

Tom and Jerry are friends. Neither Tom nor Jerry is available.

'And' = plural verb. 'Neither...nor' = verb matches the nearest subject.
⚠️ Collective:

The team is winning. (American) The team are winning. (British)

Collective nouns: American English treats as singular, British as plural
❌ Common Error:

There is too many problems with this plan.

Wrong: 'problems' is plural. Should be: 'There are too many problems.'
💡 Rule:

Find the TRUE subject (ignore prepositional phrases), then match the verb.

Cross out 'of...' phrases to find the real subject

Why Do People Confuse Them?

The #1 cause of agreement errors is prepositional phrases between subject and verb that contain a noun of different number: 'The box [of chocolates] is...' The brain sees 'chocolates' (plural) right before the verb and reaches for 'are.' Mentally crossing out prepositional phrases reveals the true subject.

Agreement Review Workflow

Use this workflow when a sentence sounds almost right but the verb feels uncertain. It works best before you polish punctuation or style.

  1. Underline the full subject. Include all words that describe the subject before the verb.
  2. Find the head noun. Decide which noun controls the verb.
  3. Bracket interrupting phrases. Temporarily ignore phrases such as of the reports, with the files, and near the deadline.
  4. Check compound logic. Use a plural verb for most and subjects; check the nearest noun for or and nor.
  5. Review special subjects. Check indefinite pronouns, collective nouns, amounts, titles, and there is/are structures.

Mini Edits by Writing Context

Agreement mistakes are especially visible in polished writing because the rest of the sentence can sound professional. These edits show how the rule works in real contexts.

Business email

Before:

The list of contract changes are attached for review.

After:

The list of contract changes is attached for review.

The subject is list, so the verb is singular.

Academic writing

Before:

Each of the studies show a similar pattern.

After:

Each of the studies shows a similar pattern.

Each is singular even when the phrase after it contains a plural noun.

Support documentation

Before:

There is two ways to reset your password.

After:

There are two ways to reset your password.

The real subject after there is plural: ways.

Public copy

Before:

Your privacy and account security matters.

After:

Your privacy and account security matter.

Two subjects joined by and usually take a plural verb.

Special Agreement Patterns

Some subjects do not follow the simple noun-before-verb habit. These patterns are common in reports, emails, and documentation.

Pattern Agreement Choice Example
Amounts as one unit Often singular Ten dollars is enough for the fee.
Titles of works Usually singular Grammar Rules is the title of the guide.
A number of Usually plural A number of users are waiting.
The number of Usually singular The number of users is increasing.
None Depends on meaning and style None of the data is missing. None of the files are missing.

Full Diagnosis Example

Agreement errors often hide inside a long subject. Work through the sentence in layers before choosing the verb.

Original sentence

Draft:

The list of contract terms, approval notes, and client comments are attached to the email.

The verb are is attracted to the plural nouns near it: terms, notes, and comments. But those nouns sit inside a phrase after of.

Step-by-step repair

  1. Find the full subject: The list of contract terms, approval notes, and client comments.
  2. Find the head noun: list.
  3. Choose the verb: list is singular, so the verb is is.
Revised:

The list of contract terms, approval notes, and client comments is attached to the email.

The revised sentence agrees with the true subject, not the nearest plural nouns.

Words That Often Control Agreement

Some words frequently decide the verb even when other nouns appear nearby. Learn these controls and many agreement errors become easier to catch.

Each and every

Each and every are usually singular because they focus on individual members one at a time.

Clear:

Each of the reports needs a summary.

All, some, most, none

These words can be singular or plural depending on the noun they refer to.

Clear:

Some of the data is missing. Some of the files are missing.

One of

One of usually takes a singular main verb because the subject is one.

Clear:

One of the reviewers has a question.

One of the people who

Inside the relative clause, the verb may agree with the plural noun before who.

Clear:

She is one of the reviewers who have asked for more data.

Fast Agreement Tests

Use these quick tests when the verb sounds wrong but you cannot immediately explain why.

Test How to Use It Example
Cross-out test Temporarily remove prepositional phrases between subject and verb. The packet of forms is ready.
Head-noun test Reduce the subject to its core noun. The explanation of delays is clear.
Nearest-noun test Use it only with either/or and neither/nor structures. Either the analysts or the manager is joining.
There test Look after there is/are to find the real subject. There are two options.
Unit test Ask whether a group or amount acts as one unit. Five minutes is enough for the setup.

Agreement in Edited Drafts

Agreement errors often appear after revision. A sentence may begin with one subject, then a writer inserts a phrase, changes a noun, or moves a clause without rechecking the verb.

After adding detail

When you add an of phrase, recheck the original subject.

Before:

The folder are ready.

After:

The folder of signed forms is ready.

After changing singular to plural

If you change the subject from singular to plural, update the verb too.

Before:

The reviewers is ready.

After:

The reviewers are ready.

After moving a phrase

Moving a phrase closer to the verb can make the wrong noun sound like the subject.

Check:

The decision, along with the supporting notes, is final.

After simplifying a sentence

When you split a sentence, each new sentence needs its own subject-verb check.

Check:

The risks are known. The mitigation plan is ready.

When Grammarlyzer Helps

Grammarlyzer can flag many subject-verb mismatches, especially in present-tense sentences where the wrong verb form is visible. It is helpful for first-pass checks on emails, essays, reports, and public pages.

Use the checker as a signal, not as the final judge. When it flags agreement, find the true subject yourself and decide whether any nearby phrase is distracting the verb. This is especially important with collective nouns, either/or structures, and sentences that contain several prepositional phrases.

Good uses for the checker

  • Finding simple mismatches such as the reports is or the report are.
  • Catching repeated agreement errors across a long draft.
  • Slowing down final review before client-facing or academic writing is published.

When the checker is not enough

  • It may not know whether your style treats a collective noun as one unit or many members.
  • It may need human confirmation when the subject is far from the verb.
  • For legal, academic, or technical claims, verify the final sentence manually.

American and British Style Notes

Some agreement choices depend on style. The most common difference involves collective nouns. American English usually treats a collective noun as singular when the group acts as one unit. British English more often allows plural agreement when the members are acting individually.

American default

The team is meeting at noon is the safer default for most US business, academic, and web copy because the team is treated as one unit.

British option

The team are debating the proposal can be acceptable in British English when the sentence emphasizes the members acting separately.

House style

For a company, school, or publication, consistency matters more than switching styles sentence by sentence. Choose the style expected by your audience and keep it across the page.

Rewrite option

If the choice feels awkward, rewrite with team members, committee members, or staff members so the plural agreement is obvious.

Full Agreement Diagnosis Example

Use this example to see how agreement decisions stack together in a real sentence.

Original sentence

Draft:

The number of support tickets, refund requests, and account questions are increasing every week.

The plural nouns near the verb make are sound tempting, but the controlling subject is number.

Step-by-step repair

  1. Find the full subject: The number of support tickets, refund requests, and account questions.
  2. Find the head noun: number.
  3. Ignore the of phrase: tickets, requests, and questions are not the subject of the main verb.
  4. Choose the verb: number is singular, so use is.
Revised:

The number of support tickets, refund requests, and account questions is increasing every week.

If that sentence still feels heavy, rewrite for readability: Support tickets, refund requests, and account questions are increasing every week. The rewrite changes the subject from number to the three plural items, so are becomes correct.

Agreement Review Checklist for Real Drafts

Agreement errors often survive spell check because every individual word is valid. The fix is to locate the real subject before looking at the verb.

Use this order

  • Underline the complete subject, then identify the head noun that controls the verb.
  • Ignore prepositional phrases such as of the reports, with the files, or near the desks.
  • Check compound subjects separately: and usually makes the subject plural, while or and nor often follow the nearer noun.
  • Decide whether collective nouns are being treated as one unit or as individual members.

When the checker helps

Grammarlyzer can catch many subject-verb mismatches, especially with simple nouns and present-tense verbs. For complex subjects, use the suggestion as a signal, then verify the true subject yourself.

Paste the whole sentence, not only the phrase around the verb, because agreement often depends on words several positions earlier. If Grammarlyzer flags the verb, bracket the middle phrases and test the subject again before accepting the correction.

Final manual pass

  • Search for of, with, and along with phrases near verbs; these often introduce distracting nouns.
  • Check there is and there are separately because the real subject appears after the verb.
  • Review every each, every, one of, a number of, and the number of construction.
  • For public or client-facing writing, keep American or British collective-noun style consistent across the whole page.

This final pass is small but high value. Agreement errors are easy for readers to notice because they affect the sentence skeleton, not just a decorative word choice.

When a sentence still feels awkward after the verb is corrected, rewrite the subject instead of forcing the original shape. For example, The number of open issues is rising is correct, but Open issues are rising may be clearer in a status update. Correct agreement is the floor; readable structure is the goal.

That rewrite habit matters because readers notice awkward correctness almost as quickly as they notice outright errors in important writing. Clean agreement should support clarity for every reader in public text and final online documents, not merely satisfy a narrow grammar rule in isolation.

For shared documents, add recurring agreement traps to a team checklist. If several writers keep using there is before plural subjects or matching verbs to the nearest noun, a short review note prevents the same issue from returning in every draft and keeps published pages more consistent across future edits.
