basic fundamentals/necessities (fundamentals/necessities)

Subject-verb agreement requires the verb to match the grammatical subject in number (singular/plural) and person. Most errors happen when the real subject is hidden by modifiers, phrases, or inverted word order.

Below are concise rules, many natural wrong/right pairs for work, school, and casual contexts, practical rewrites, and quick checks you can use on the spot.

Quick answer: make the verb match the true subject

Identify the grammatical subject, ignore nearby nouns or modifiers, and choose a verb that matches its number and person.

Singular subject → singular verb: The committee meets on Tuesday.
Plural subject → plural verb: The committees meet on Tuesday.
Ignore intervening phrases: The cost of repairs is high (not are).
For either/or and neither/nor, the verb agrees with the noun closest to it.

Core rules (short and actionable)

Find the subject before you conjugate. Skip prepositional phrases, parenthetical modifiers, and objects when deciding number.

Watch these traps: collective nouns, compound subjects, indefinite pronouns, and sentences starting with there.

Subjects joined by and = plural (Jack and Jill are here).
Subjects joined by or/nor = verb matches the closer subject (Either the manager or the assistants are available).
Indefinite pronouns (everyone, each, somebody) are singular and take singular verbs.

Wrong: The box of tools are in the garage.
Right: The box of tools is in the garage.
Wrong: Everyone have a ticket.
Right: Everyone has a ticket.
Wrong: There is many reasons to wait.
Right: There are many reasons to wait.

Real usage - work examples (emails, reports, meetings)

Business writing often hides the subject in long noun phrases. Move the subject next to the verb or rewrite for clarity.

Treat a collective noun as singular when you mean the group as a single unit: The board has approved the policy.
If you mean individual members, use plural: The board were arguing among themselves.

Work - Wrong: The team have completed the audit and will present it tomorrow.
Work - Right: The team has completed the audit and will present it tomorrow.
Work - Wrong: The list of candidates are attached.
Work - Right: The list of candidates is attached.
Work - Wrong: Either the manager or the assistants is available for the call.
Work - Right: Either the manager or the assistants are available for the call.

Real usage - school examples (assignments, presentations, reports)

Academic readers expect precise agreement. When in doubt, recast sentences so the subject and verb are obvious.

Use singular verbs with each and every: Every chapter contains examples.
With neither/nor, match the verb to the closer noun: Neither the teacher nor the students were ready.

School - Wrong: The group of students are studying for the exam.
School - Right: The group of students is studying for the exam.
School - Wrong: Neither the professor nor the students was at the seminar.
School - Right: Neither the professor nor the students were at the seminar.
School - Wrong: Five miles is too far for most people to run every day? (incorrect when intended plural)
School - Right: Five miles is too far for most people to run every day.

Real usage - casual speech and quick texts

Informal speech tolerates shortcuts that read poorly in writing. Fix contractions and object pronoun subjects in written texts.

Avoid there's before plural nouns in writing: use there are.
Use subject pronouns in subject position: Jake and I (not Me and him).

Casual - Wrong: There's three people waiting for you outside.
Casual - Right: There are three people waiting for you outside.
Casual - Wrong: Me and Jake is heading to the game.
Casual - Right: Jake and I are heading to the game.
Casual - Wrong: Everybody want pizza tonight?
Casual - Right: Everybody wants pizza tonight?

Try your own sentence

Test the whole sentence, not just a phrase. Context often makes the correct verb clear.

Rewrite help: copy-and-paste fixes

When a sentence trips you up, use one of three moves: bring the subject next to the verb, replace vague starters like there is/are, or switch to active voice.

Move the subject next to the verb: "The list of items is..." instead of "The list of items are...".
Replace there is/are with the real subject at the start.
Use active voice so agreement is obvious.

Rewrite:
Wrong: There's many issues with the report. |
Rewrite: The report has many issues.
Rewrite:
Wrong: A number of students is missing. |
Rewrite: A number of students are missing.
Rewrite:
Wrong: The committee were split on the vote. |
Rewrite: The committee was split on the vote. (Or) The committee members were split on the vote.
Rewrite:
Wrong: Neither the coach nor the players was ready. |
Rewrite: Neither the coach nor the players were ready.

Memory tricks and quick proofreading checks

Use short tests to catch most errors without digging into rules.

Isolate the subject: remove of... and other modifiers, then read "Subject + verb" aloud.
Swap into a short sentence: "The list is" vs "The lists are" - which sounds right?
Watch signal words: every/each → singular; and → plural; or/nor → nearest noun.

Usage: Quick test: Remove the modifier in "The leader of the teams ____." Use "The leader is" → singular verb.

Hyphenation, spacing, and contractions that mislead you

Expanding contractions and checking hyphenation reveals the true subject and prevents misreading.

Expand contractions while proofreading: there's → there is.
Hyphenated modifiers can bury the real subject-rephrase or move the subject out of the modifier.
Spacing errors rarely change grammar but can mislead readers in headlines or posts.

Wrong: There's two-year warranty on these items.
Right: There is a two-year warranty on these items. / These items have a two-year warranty.
Wrong: The five year-old players is ready.
Right: The five-year-old players are ready.

Similar mistakes and quick fixes

Agreement problems often appear alongside pronoun mismatch, tense slips, and misplaced modifiers. Fix agreement first, then check these areas.

Pronoun-antecedent: plural antecedent → plural pronoun (Students → their).
Tense consistency: keep the same tense across linked clauses.
Misplaced modifier: ensure modifiers attach to the correct noun so you identify the right subject.

Wrong: Each student must hand in their paper on Friday.
Right: Each student must hand in his or her paper on Friday. / Each student must hand in their paper on Friday (singular they widely accepted).
Wrong: She was going to class and studies for the exam.
Right: She was going to class and studying for the exam.

FAQ

How do I choose between there is and there are?

Use there is with singular nouns and there are with plural nouns. Speakers often say there's for both; avoid that in formal writing.

Should collective nouns be singular or plural?

Use singular when the group acts as one unit (The team wins). Use plural when you mean individual members (The team are arguing). Stay consistent.

What about each, every, everyone - singular or plural?

These are grammatically singular and take singular verbs: Every student is responsible. Many writers use singular they for inclusivity: Everyone should bring their ID.

How do neither/nor and either/or work?

The verb agrees with the subject closest to it: Neither the CEO nor the employees were happy. Either the supervisors or the manager is coming.

Is singular they acceptable to avoid awkward agreement?

Yes. Singular they is widely accepted for gender-neutral or indefinite references and often avoids awkward rewrites.
