This subject-verb agreement lesson for B1/B2 intermediate ESL learners covers every essential rule — from singular and plural subjects to tricky cases like collective nouns, indefinite pronouns, and inverted sentences — plus a full 30-question interactive quiz with detailed explanations.
One of the most common grammar errors intermediate English learners make is subject-verb disagreement — using a plural verb with a singular subject, or vice versa. This happens not just with simple sentences, but especially in complex structures where the subject is hard to identify. By the end of this lesson, you will understand exactly how to match every subject with the correct verb form.
Whether you are preparing for an English proficiency exam like IELTS or Cambridge B2 First, or simply want to write and speak more accurately, mastering subject-verb agreement rules is one of the highest-impact grammar skills you can build at the intermediate level.
📌 Quick Answer: Subject-Verb Agreement at a Glance
- Singular subject = singular verb (adds -s/-es) → She works every day.
- Plural subject = plural verb (no -s) → They work every day.
- Compound subject (and) = usually plural verb → Tom and Lisa are here.
- Indefinite pronouns (everyone, nobody) = singular verb → Everyone knows the answer.
- Collective nouns (team, committee) = singular verb in American English → The team is ready.
Key Rule: Always identify the true subject of the sentence — ignore phrases between the subject and verb — then match the verb to that subject.

What Is Subject-Verb Agreement? Definition and Function for Intermediate ESL Learners
Subject-verb agreement is the grammatical rule that requires the verb in a sentence to match the subject in number (singular or plural) and person (first, second, or third). In English, this agreement is most visible in the third person singular present tense, where the verb takes an -s or -es ending.
At the B1/B2 level, subject-verb agreement goes far beyond simple sentences like He runs or They run. Intermediate learners must handle complex structures — sentences with intervening phrases, inverted word order, compound subjects, and special noun groups — all of which can disguise the true subject and lead to agreement errors.
Understanding this rule is critical because subject-verb disagreement is immediately noticeable to native English speakers and examiners. It affects the clarity, professionalism, and accuracy of both written and spoken English at the intermediate level and beyond.
| Subject Type | Verb Form | Example |
|---|---|---|
| Singular noun / He, She, It | Verb + -s/-es | The student studies hard. |
| Plural noun / They | Base verb (no -s) | The students study hard. |
| I / You / We | Base verb (no -s) | I study every evening. |
| Compound (X and Y) | Plural verb | Ana and Pedro study together. |
Key Point: The agreement rule applies in the present simple and with the verb be in all tenses. Always locate the subject first — do not be distracted by nearby nouns.
The Core Rules: How to Use Subject-Verb Agreement Correctly in English
The foundation of subject-verb agreement in English is straightforward: a singular subject takes a singular verb, and a plural subject takes a plural verb. However, at the B1/B2 level, several structures make this more challenging. The most dangerous trap is the intervening phrase — a prepositional phrase or relative clause placed between the subject and the verb that can make learners choose the wrong verb form.
For example: The quality of these products is very high. — The subject is quality (singular), not products. The phrase of these products is an intervening phrase and does not affect the verb. This single rule accounts for a huge proportion of B1/B2 agreement errors in both writing and speaking.
A second core rule involves the verb be, which has the most irregular agreement forms in English. Learners must know: am (I), is (he/she/it), are (you/we/they) in the present, and was (I/he/she/it), were (you/we/they) in the past. These forms must be automatic at the B1/B2 level.
| Rule | Structure | Correct Example | Common Error |
|---|---|---|---|
| Intervening phrase | Subject + [of/with/as well as…] + Verb | The box of chocolates is on the table. | |
| Either/Or subjects | Either X or Y + Verb agrees with Y | Either the students or the teacher is wrong. | |
| Neither/Nor subjects | Neither X nor Y + Verb agrees with Y | Neither the manager nor the staff were informed. | |
| There + be | There + be agrees with the noun following | There are three reasons for this. |
Important Exception: When two singular subjects are joined by or or nor, the verb is singular: Neither John nor Mary was there. But when one subject is plural, the verb agrees with the subject closest to it.
Practice Tip: When proofreading, underline every subject in your writing and draw an arrow to its verb. Ask yourself: is this subject singular or plural? Then check the verb form. This habit eliminates most subject-verb agreement errors instantly.
The 6 Types of Subject-Verb Agreement Every Intermediate Learner Must Know
| Type | Key Pattern | Verb Agreement |
|---|---|---|
| 1. Basic singular/plural | Simple noun + verb | Matches number of subject |
| 2. Compound subjects | X and Y / Either X or Y | Plural (and) / Closest subject (or/nor) |
| 3. Collective nouns | team, class, family, committee | Singular (AmE) / context-dependent (BrE) |
| 4. Indefinite pronouns | everyone, nobody, each, either | Always singular |
| 5. Inverted sentences | There is/are / Here comes/come | Agrees with the noun after the verb |
| 6. Relative clauses | who/which/that + verb | Agrees with the antecedent noun |
Type 1: Basic Singular and Plural Agreement
This is the foundation. A singular subject (one person, thing, or idea) takes a verb ending in -s or -es in the third person present. A plural subject takes the base form of the verb.
- The dog barks every morning. (singular subject → singular verb)
- The dogs bark every morning. (plural subject → plural verb)
- A new policy requires all staff to sign in. (singular subject)
- New policies require all staff to sign in. (plural subject)
Position Rule: The verb directly follows the subject in most English sentences. At B1/B2, watch for modifiers placed between subject and verb.
Common Mistake: The list of items were checked. → Correct: The list of items was checked. (Subject = list, singular)
Type 2: Compound Subjects
When two subjects are joined by and, the verb is almost always plural. When joined by or, nor, either…or, or neither…nor, the verb agrees with the subject closest to it — this is called the proximity rule.
- The teacher and the students are in the room. (and → plural)
- Either the director or the managers are responsible. (closest = managers → plural)
- Neither the students nor the teacher was prepared. (closest = teacher → singular)
- Not only the price but also the quality matters. (closest = quality → singular)
Common Mistake: Either the president or the ministers is attending. → Correct: Either the president or the ministers are attending.
Type 3: Collective Nouns
Collective nouns refer to a group of people or things as a single unit. In American English, they always take a singular verb. In British English, they can take a plural verb when the group members are acting individually.
- The committee has reached a decision. (AmE — acting as one unit)
- The team are arguing among themselves. (BrE — members acting individually)
- The government is planning new legislation. (AmE)
- The jury have disagreed on the verdict. (BrE)
Common Mistake: Mixing AmE and BrE conventions in the same text — choose one style and be consistent throughout your writing.
Type 4: Indefinite Pronouns
Indefinite pronouns like everyone, everybody, someone, anybody, nobody, each, either, neither, one always take a singular verb, even though they may seem to refer to more than one person. This is one of the most tested points at the B1/B2 level.
- Everyone is welcome to attend.
- Nobody knows the answer.
- Each of the students has submitted the assignment.
- Neither of the options is acceptable.
Common Mistake: Everyone have their own opinion. → Correct: Everyone has their own opinion.
Type 5: Inverted Sentences (There is / There are)
In sentences beginning with there or here, the verb comes before the subject. The verb must agree with the noun that follows it, not with the word there.
- There is a problem with the system. (problem = singular)
- There are several problems with the system. (problems = plural)
- Here comes the bus. (bus = singular)
- There were many reasons for the delay. (reasons = plural)
Common Mistake: There's many opportunities available. → Correct: There are many opportunities available.
Type 6: Relative Clauses (Who / Which / That)
When a relative pronoun (who, which, that) is the subject of a relative clause, the verb in that clause must agree with the antecedent — the noun the relative pronoun refers back to.
- It is the students who are responsible. (who refers to students → plural)
- It is the student who is responsible. (who refers to student → singular)
- The report that was submitted is incomplete. (that refers to report → singular)
- The reports that were submitted are incomplete. (that refers to reports → plural)
Common Mistake: She is one of the teachers who teaches grammar. → Correct: She is one of the teachers who teach grammar. (who refers to teachers → plural)
Key Differences: Subject-Verb Agreement — The Confusing Pairs Intermediate Learners Always Get Wrong
Each / Every vs. All / Both
Each and every are always followed by a singular verb, because they focus on individual members of a group one at a time. All and both are followed by a plural verb because they refer to the group as a whole.
- Each student has a different learning style. ✅
- Every question counts towards your final grade. ✅
- All students have submitted their essays. ✅
- Both answers are correct. ✅
Each of the answers are correct.❌ → Each of the answers is correct. ✅
The Number of vs. A Number of
This is a classic B2-level trap. The number of is a singular expression (focus is on the number itself), so it takes a singular verb. A number of means "several" or "many" and takes a plural verb.
- The number of applicants has increased significantly. ✅
- A number of applicants have withdrawn their applications. ✅
The number of errors are surprising.❌ → The number of errors is surprising. ✅
None of vs. Neither of
None of can take either a singular or plural verb in modern English, though the singular is more formal. Neither of is traditionally singular but increasingly accepts plural in informal use.
- None of the information is accurate. (formal/singular) ✅
- None of the students were absent. (acceptable in informal use) ✅
- Neither of the candidates was suitable. (formal) ✅

Frequently Asked Questions about Subject-Verb Agreement in English Grammar
What is the basic rule of subject-verb agreement in English?
The basic rule is that a singular subject requires a singular verb, and a plural subject requires a plural verb. In the present simple tense with a third-person singular subject (he, she, it, or any singular noun), the verb adds -s or -es. This rule applies to all English verbs except modal verbs.
For example: The teacher explains the rules clearly. (singular) vs. The teachers explain the rules clearly. (plural). The verb be has special forms: am, is, are (present) and was, were (past) — these must be memorised carefully.
Why is subject-verb agreement difficult for intermediate English learners?
At the B1/B2 level, agreement becomes difficult because the subject is not always directly next to the verb. Intervening phrases (like of the students, as well as the manager, or together with her colleagues) can mislead learners into agreeing the verb with the wrong noun. Additionally, special structures like collective nouns, indefinite pronouns, and inverted sentences all have their own rules that differ from the basic pattern.
Another challenge is that some structures look plural but are grammatically singular — for example, everyone, each of the students, the number of applications. Intermediate learners must recognise these patterns by repeated exposure and deliberate practice.
Does "everyone" take a singular or plural verb?
Everyone always takes a singular verb in standard English grammar. Although everyone refers to many people, it is grammatically classified as a singular indefinite pronoun. The same rule applies to everybody, someone, somebody, anyone, anybody, no one, nobody, each, and every.
Correct: Everyone has the right to express an opinion. ✅ Incorrect: Everyone have the right… ❌. Note: In informal spoken English, everyone … their is widely used for gender neutrality: Everyone should bring their own lunch.
What is the difference between "a number of" and "the number of" in subject-verb agreement?
A number of means "several" or "many" and is treated as a plural expression, taking a plural verb. The number of refers to a quantity as a single figure and is treated as a singular expression, taking a singular verb. This distinction is a classic B2-level grammar point frequently tested in proficiency exams.
Examples: A number of students have complained about the timetable. (plural) vs. The number of complaints has risen sharply. (singular). A useful memory trick: a number of = many (plural); the number of = the total/figure (singular).
How does subject-verb agreement work in relative clauses?
In a relative clause introduced by who, which, or that, the verb must agree with the antecedent — the noun that the relative pronoun refers to. If the antecedent is singular, use a singular verb in the relative clause. If it is plural, use a plural verb.
The most confusing case is the structure one of the [plural noun] who/that…. In this case, the verb in the relative clause is plural because who/that refers to the plural noun, not to one. Example: She is one of the researchers who have published in Nature. (have, not has — because who refers to researchers)
