Subject-Verb Agreement Rules in English Grammar

Introduction

Subject-verb agreement is one of the most important foundations of clear English. When your subject and verb match in number (singular or plural), your sentences sound natural and professional. Getting this right helps you avoid confusing your reader and makes your writing much stronger.

What Is Subject-Verb Agreement?

Subject-verb agreement means that the subject of a sentence and its verb must agree in number. A singular subject takes a singular verb, and a plural subject takes a plural verb. For example, “She runs” (singular) and “They run” (plural) show correct agreement. The tricky part is that subject-verb agreement can be affected by words that come between the subject and the verb, or by special subjects like indefinite pronouns.

Rules

1. Singular subjects take singular verbs. Example: The dog barks loudly.
2. Plural subjects take plural verbs. Example: The dogs bark loudly.
3. Compound subjects joined by “and” are usually plural. Example: Tom and Jerry are friends.
4. Compound subjects joined by “or” or “nor” agree with the subject closest to the verb. Example: Neither the teacher nor the students agree.
5. Indefinite pronouns like “everyone,” “someone,” “nobody” are always singular. Example: Everyone is ready.
6. Collective nouns (team, family, group) can be singular or plural depending on meaning. Example: The team plays well (as a unit) vs. The team argue among themselves (as individuals).
7. Subjects separated from the verb by prepositional phrases still determine agreement. Example: The box of chocolates is on the table. (subject = box, not chocolates)
8. Words like “each” and “every” are always singular. Example: Each student has a book.
9. Titles and names of works are singular. Example: “The Adventures of Huckleberry Finn” is a classic.
10. Subjects expressing amounts (time, money, distance) are usually singular. Example: Ten dollars is too much.

How to Use It

Follow these simple steps to ensure correct subject-verb agreement every time:

1. Identify the subject. Look for the main noun or pronoun doing the action. Ignore any words that come between the subject and the verb (like prepositional phrases).
2. Determine if the subject is singular or plural. Check for compound subjects, indefinite pronouns, and collective nouns carefully.
3. Choose the correct verb form. For present tense, add an “-s” or “-es” to the base verb for singular third-person subjects (he, she, it). Do not add “-s” for plural subjects or for “I” and “you.”
4. Check for tricky subjects. Remember that “everyone,” “someone,” “nobody,” “each,” and “either/neither” are singular. Also, watch for subjects like “the number” (singular) vs. “a number” (plural).
5. Read your sentence aloud. If it sounds wrong, recheck the subject. For example, “The list of items are long” sounds odd because “list” is singular—the correct version is “The list of items is long.”

Examples in Sentences

• The cat sleeps on the sofa every afternoon.
• My sisters love to watch horror movies.
• Neither the manager nor the employees know about the meeting.
• Everyone in the class has completed the assignment.
• Ten miles is a long distance to walk.
• The team is celebrating its victory.
• A box of crayons sits on the desk.
• Mathematics is my favorite subject.
• Each of the players plays a different position.
• The news is not good today.
• She and her brother are coming to the party.
• Either the red shirt or the blue pants match your jacket.

Common Mistakes

• Mistake 1: ❌ The group of students are noisy.
  ✅ Correct: The group of students is noisy. (subject = group, singular)
• Mistake 2: ❌ Everyone have finished their lunch.
  ✅ Correct: Everyone has finished their lunch. (everyone = singular)
• Mistake 3: ❌ The list of rules are on the wall.
  ✅ Correct: The list of rules is on the wall. (subject = list, singular)
• Mistake 4: ❌ Neither the teacher nor the student know the answer.
  ✅ Correct: Neither the teacher nor the student knows the answer. (closest subject = student, singular)
• Mistake 5: ❌ Each of the cars are expensive.
  ✅ Correct: Each of the cars is expensive. (each = singular)

Quick Summary

• Singular subject = singular verb. Add “-s” to the verb for he/she/it in present tense.
• Plural subject = plural verb. Do not add “-s” for they/we/you/I.
• Watch for prepositional phrases. The subject is never inside a prepositional phrase.
• Indefinite pronouns (everyone, someone, nobody, each) are always singular.
• Compound subjects with “and” are usually plural.
• Compound subjects with “or/nor” agree with the nearest subject.
• Collective nouns can be singular or plural based on context.
• Amounts and titles are usually singular.

Conclusion

Mastering subject-verb agreement takes practice, but it is one of the fastest ways to improve your English writing and speaking. Start by focusing on the basic rule: singular subjects take singular verbs, and plural subjects take plural verbs. Keep an eye on tricky subjects like indefinite pronouns and collective nouns, and soon it will become second nature.

FAQ

1. What is the most common subject-verb agreement mistake?

The most common mistake is when a singular subject is followed by a prepositional phrase containing a plural noun, and the writer accidentally makes the verb agree with that plural noun. For example, “The box of chocolates are delicious” is wrong because “box” is the subject (singular), so the correct verb is “is.”

2. How do I know if a collective noun is singular or plural?

It depends on meaning. If the group acts as a single unit, use a singular verb: “The committee decides tomorrow.” If the members act individually, use a plural verb: “The committee disagree on the plan.” In American English, collective nouns are usually singular; in British English, they are more often plural.

3. Do “none” and “any” take singular or plural verbs?

It depends on the noun that follows. If the noun is uncountable or singular, use a singular verb: “None of the water is drinkable.” If the noun is countable and plural, use a plural verb: “None of the students are ready.” Similarly, “Any of the cake is yours” vs. “Any of the books are available.”

4. What about subjects like “the number” vs. “a number”?

“The number” is always singular: “The number of participants is 20.” “A number” is always plural: “A number of participants are arriving late.” This is a fixed rule, so memorizing it will help you avoid a common error.
