Subject-Verb Agreement in English Grammar: Essential Rules (With Examples & Quiz)

In English grammar, Subject-Verb Agreement is the foundational rule stating that a verb must agree in number (singular or plural) with its subject. A singular subject requires a singular verb, while a plural subject requires a plural verb.

While this concept sounds simple in principle, complex sentence structures, prepositional phrases, collective nouns, and indefinite pronouns often confuse writers. Mastering subject-verb agreement ensures your writing is clear, precise, and grammatically impeccable.

In this comprehensive tutorial, we break down the 10 essential rules of subject-verb agreement, highlight tricky edge cases, and test your skills with an interactive quiz.

1. The Core Rule: Singular vs. Plural Matches

The basic rule states that singular subjects take singular verbs, and plural subjects take plural verbs.

• Singular: The student works hard. (Singular subject 'student' + singular verb 'works')
• Plural: The students work hard. (Plural subject 'students' + plural verb 'work')

---

2. Rule 1: Words Separating the Subject and Verb

Prepositional phrases or clause interruptions coming between the subject and the verb do not change the number of the subject. Ignore the interrupting words when choosing the verb form.

• Incorrect: The box of chocolates are on the counter.
• Correct: The box of chocolates is on the counter. (Subject is box, not chocolates).
• Correct: The manager, along with her assistant, attends the meeting. (Subject is manager).

3. Rule 2: Compound Subjects with "And"

Two or more subjects joined by and usually take a plural verb. However, if the subjects refer to a single idea, item, or person, use a singular verb.

• Plural: Rahul and Priya are leading the project.
• Singular (Single concept): Rice and curry is his favorite meal.
• Singular (Same person): The CEO and founder has arrived. (Refers to one individual holding both titles).

---

4. Rule 3: Subjects Joined by "Or", "Nor", or "Either...Or"

When subjects are connected by or, nor, either...or, or neither...nor, the verb must agree with the subject closest to the verb.

• Example 1: Neither the director nor the actors were present at the rehearsal. (Verb agrees with plural 'actors').
• Example 2: Neither the actors nor the director was present at the rehearsal. (Verb agrees with singular 'director').

5. Rule 4: Indefinite Pronouns (Singular vs. Plural)

Indefinite pronouns require special attention regarding subject-verb agreement:

A. Always Singular Indefinite Pronouns

Everyone, someone, anyone, no one, everybody, somebody, anybody, nobody, each, either, neither, everything, something, anything, nothing.

• Example: Everyone in the hall was listening intently.
• Example: Each of the candidates has submitted a resume.

B. Always Plural Indefinite Pronouns

Both, few, many, several.

• Example: Few have mastered the complex formula.

C. Context-Dependent Pronouns (SANAM Rule)

Some, Any, None, All, Most. These pronouns depend on the noun following in the prepositional phrase ("of the..."):

• Uncountable Noun: Some of the sugar was spilled.
• Countable Plural Noun: Some of the apples were spoiled.

---

6. Rule 5: Collective Nouns

Collective nouns (e.g., team, committee, family, jury, audience, staff) take a singular verb when the group acts as a single cohesive unit, but a plural verb when members act individually.

• Acting as a unit: The committee has approved the budget proposal.
• Acting individually: The committee are divided in their opinions regarding the policy.

---

7. Rule 6: Distances, Periods of Time, and Money

Nouns expressing specific amounts of money, periods of time, or distances are considered a single quantity and take singular verbs.

• Example 1: Five miles is a long distance to walk every morning.
• Example 2: Ten thousand rupees was spent on the event decorations.
• Example 3: Three hours is enough time to complete the examination.
