A verb that agrees with the subject matches number, so singular subjects take singular verbs and plural subjects take plural verbs.
Subject–verb agreement sounds like a classroom rule, yet it shows up in real writing all the time: essays, emails, application letters, lab reports, even quick texts. When the verb form clashes with the subject, readers stumble. On tests, it can cost points in a blink.
This guide keeps the rule plain, then walks through sentence patterns that trip people up. You’ll get fast checks you can run in seconds, plus models you can copy while drafting.
| Subject Pattern | Verb Form That Fits | Quick Check |
|---|---|---|
| One person or thing | Singular verb in present tense (often ends in -s) | Swap in “he/she/it” |
| Two subjects joined by “and” | Plural verb | Swap in “they” |
| Two subjects joined by “or/nor” | Verb matches the closer subject | Check the noun nearest the verb |
| Collective noun (team, class, family) | Often singular | Is the group acting as one unit? |
| Indefinite pronoun (each, anybody, nobody) | Often singular | Can you say “each one”? |
| Phrase between subject and verb | Verb matches the subject, not the nearby noun | Cross out the middle phrase |
| Amounts and measurements | Singular when treated as one total | Ask “one total” or “separate units”? |
| Titles of works | Singular, even if the title looks plural | It’s one title |
| There is/there are openings | Verb matches the noun after the verb | Find what “there” points to |
| Who/that clauses | Verb matches the word the clause refers to | Ask “who is doing it?” |
Verb That Agrees With The Subject
Agreement means the verb form fits the subject’s number: one or many. In the present tense, English adds an -s to many third-person singular verbs: she runs, it works, the plan changes. Plural subjects skip that ending: they run, the plans change.
Agreement also connects to person: I am, you are, he is. Most verbs don’t change much by person, yet be changes a lot.
Find The Real Subject First
Many errors come from picking the wrong subject. Ask: “Who or what is doing the verb?” Then check if that subject is singular or plural.
Watch out for nouns that sit right next to the verb but are not the subject. Prepositional phrases often slide between the subject and verb: of, with, in, along, between.
- The list of items is on the desk. (Subject: list)
- The boxes of paper are in the hall. (Subject: boxes)
Use A Fast Swap Test
Swap the subject with a pronoun, then pick the verb form that fits.
- The coach of the players is ready. → He is ready.
- The coach and the players are ready. → They are ready.
Know The Odd Forms
The verb be is the big one: I am, you are, he/she/it is, we are, they are. The verb have also shifts: he has but they have.
Past tense usually sidesteps agreement for most verbs: I walked, they walked. Still, was/were can trip writers: the group was vs. the groups were.
Picking Verbs That Match Their Subjects In Tough Spots
Once you can spot the true subject, the next challenge is handling patterns where the subject is not a single, clean noun.
Subjects Joined By “And”
Two singular subjects linked by and usually take a plural verb.
- Jamila and Noor study after class.
- The phone and the charger belong to me.
One twist: when two nouns joined by and name one person or one thing, a singular verb can fit. My friend and roommate is moving out.
Subjects Joined By “Or” Or “Nor”
With or and nor, the verb matches the closer subject.
- Either the teacher or the students are presenting today.
- Either the students or the teacher is presenting today.
Words That Look Plural But Act Singular
Some nouns end in -s but act as singular nouns: news, mathematics, physics.
- The news is on at six.
- Mathematics is part of the program.
Other nouns are the reverse: they look singular but act plural, like police and people. You’ll write the police are and people are.
Collective Nouns
Collective nouns name a group: team, class, family, committee. Many writers treat them as singular when the group acts as one unit: The team wins tonight.
When you want to stress the members acting as separate individuals, rewrite: Team members are arguing among themselves.
Indefinite Pronouns That Lean Singular
Words like each, anybody, anyone, someone, nobody usually take singular verbs.
- Anybody wants a fair grade.
- Each of the answers is checked twice.
Indefinite Pronouns That Lean Plural
Words like many, few, several pair with plural verbs.
- Many are called, few are chosen.
- Several were absent.
All, Some, Most, None
Match the verb to the noun that follows.
- Some of the water is gone.
- Some of the bottles are gone.

Subjects With A Phrase In The Middle
Strip the phrase away and check agreement with what remains.
- The bouquet of roses smells great. (bouquet smells)
- The roses in the bouquet smell great. (roses smell)
Watch the phrases along with, together with, and as well as. They do not act like and.
Amounts, Fractions, And Measurements
Amounts and measurements often take a singular verb when treated as one total.
- Ten dollars is enough for lunch.
- Five miles is a long walk in the rain.
Use a plural verb when you mean separate units: Ten dollars are scattered on the table.
Fractions work the same way. Half of the pie is gone. Yet: Half of the slices are gone.
Titles And Names Of Works
A title is one title, even if the wording inside looks plural.
- “The Chronicles of Narnia” is on my shelf.
- “Great Expectations” is still assigned in many classes.
There Is And There Are
In sentences starting with there is or there are, the real subject comes after the verb.
- There is a problem with the file.
- There are two problems with the file.
Who, Which, That Clauses
In a clause starting with who, which, or that, the verb matches the word the clause refers to.
- She is one of the students who work late. (students work)
- She is the only one of the students who works late. (one works)
Agreement In Questions And With Helping Verbs
Agreement can feel easy in a plain statement, then you flip the sentence into a question and the word order changes. In many questions, the helping verb jumps in front of the subject. Your job is the same: match the verb form to the subject, even when the subject shows up later in the line.
Questions Where The Subject Comes After The Verb
Look at the noun right after the verb, not the first noun you see.
- Is the list of topics ready? (list is)
- Are the lists of topics ready? (lists are)
- Where are the labels for the cabinet? (labels are)
If you’re unsure, flip the question back into a statement and listen again: The list is ready.The lists are ready.
Do, Does, Did, And The Base Verb
With do and does, agreement lives on the helping verb. The main verb stays in the base form.
- Does she run? (does matches she; run stays plain)
- Do they run? (do matches they; run stays plain)
- Did he run? (did works with any subject; run stays plain)
This one rule wipes out a lot of mixed forms like “does runs.”
Modal Verbs Stay The Same
Modal verbs like can, could, may, might, must, should, will, and would do not change for number. The verb that follows stays in the base form too.
- She can write. / They can write.
- He must go. / They must go.
Ten-Sentence Edit Drill
Try this on any draft. It’s quick, and it trains your eye.
- Underline each main verb.
- Circle the subject that controls that verb.
- If a phrase sits in the middle, cross it out and recheck.
- Swap the subject with he or they and listen for the match.
- Scan questions and confirm the subject after the helping verb.
Quick Ways To Fix Agreement While Editing
You don’t need fancy grammar terms to clean up agreement. You need a repeatable routine.
Step 1: Circle The Subject And The Main Verb
Find the main verb, then ask who is doing it. Ignore extra phrases at first.
Step 2: Turn Long Subjects Into Short Ones
Shrink the subject to a pronoun, then choose the matching verb form.
- The set of instructions for new students (is/are) clear. → It (is/are) clear. → It is clear.
Step 3: Check The Verb Tense You’re In
Most agreement slips happen in the present tense. Singular third person adds -s. Plural does not.
Step 4: Watch For Four Repeat Offenders
- Prepositional phrases between subject and verb
- Or/nor pairs with a mixed singular and plural subject
- Indefinite pronouns like each and nobody
- There is/are openings
The University of Wisconsin Writing Center subject–verb agreement page lists these patterns with short reminders.
Step 5: Read It Aloud With A Pause
Put a tiny pause between subject and verb. If your tongue wants to change the verb form during that pause, double-check.
Common Agreement Errors And Clean Fixes
This table is built for quick scanning while you edit.
| Mismatch Pattern | Fix | Try This Model |
|---|---|---|
| Singular subject + plural verb | Use third-person singular in present tense | The schedule changes each week. |
| Plural subject + singular verb ending in -s | Drop the -s ending | The schedules change each week. |
| Subject hidden by “of” phrase | Match the verb to the noun before “of” | A box of pens is missing. |
| Or/nor with mixed subjects | Match the closer subject or rewrite | Either the assistants or the manager is here. |
| Each with plural meaning | Use singular verb | Each gets a turn. |
| All/some/none with unclear noun | Match the noun that follows | All of the work is done. / All of the tasks are done. |
| There is/are with a plural noun | Switch to “are” | There are three options. |
| Who/that clause points to the wrong noun | Match the noun the clause refers to | She is one of the people who work weekends. |
| Collective noun treated inconsistently | Pick one meaning and stick with it | The committee meets at noon. |
Write With Confidence Without Overthinking
Draft freely, then run a short edit pass. Circle the subject and verb, cut out the middle phrases, and do the pronoun swap when your ear hesitates.
Need a final check? Search your document for verbs ending in -s and confirm each one has a singular subject close by. Also scan for the phrase verb that agrees with the subject and make sure you can point to the subject it matches.
