Subject-Verb Agreement Rules in English

Introduction

Getting subject-verb agreement wrong is one of the fastest ways to confuse your reader. Whether you are writing an email, an essay, or a social media post, matching the subject to the verb correctly makes your English clear and professional. In this post, we will break down the rules step by step, show you common mistakes, and give you plenty of practice so you can write with confidence.

What Is Subject-Verb Agreement?

Subject-verb agreement means that the subject and the verb in a sentence must match in number. A singular subject needs a singular verb, and a plural subject needs a plural verb. For example:

• The cat runs fast. (singular subject + singular verb)
• The cats run fast. (plural subject + plural verb)

This rule sounds simple, but tricky situations—like collective nouns, indefinite pronouns, and compound subjects—can cause confusion. Let’s explore the key rules.

Rules

1. Singular subjects take singular verbs; plural subjects take plural verbs. Example: She writes every day. / They write every day.
2. Use a singular verb with indefinite pronouns like everyone, someone, nobody, each, either, neither. Example: Everyone is ready.
3. Compound subjects joined by and usually take a plural verb. Example: Tom and Jerry are friends.
4. For compound subjects joined by or or nor, the verb agrees with the subject closest to it. Example: Neither the teacher nor the students are late.
5. Collective nouns (team, family, group) can be singular or plural depending on meaning. If the group acts as one unit, use singular: The team is winning. If members act individually, use plural: The team are arguing among themselves.
6. Words like each, every, either, neither are always singular. Example: Each student has a book.
7. Expressions of quantity (half of, most of, some of) agree with the noun that follows of. Example: Half of the cake is gone. / Half of the cookies are gone.

How to Use It

Follow these steps every time you write a sentence:

1. Identify the subject. Ask yourself: Who or what is doing the action? Example: The dog barks. Subject = dog.
2. Determine if the subject is singular or plural. One dog = singular. Two dogs = plural.
3. Check for tricky subjects. Is the subject a collective noun? An indefinite pronoun? A compound subject? Adjust the verb accordingly.
4. Ignore prepositional phrases. Words like with, along with, together with, as well as do not change the number of the subject. Example: The teacher, along with her students, is going on the trip. (Subject = teacher, singular)
5. Choose the correct verb form. For present tense, add -s or -es for singular third-person subjects (he, she, it). For plural subjects, use the base form.

Examples in Sentences

• My brother plays guitar every evening.
• The children play in the park after school.

• Mathematics is my favorite subject. (singular noun ending in -s)
• The news is good today. (uncountable noun)
• One of the windows is broken.

Common Mistakes

• Mistake 1: ❌ The list of items are on the table. ✅ The list of items is on the table. (Subject = list, singular)
• Mistake 2: ❌ Neither the teacher nor the student know the answer. ✅ Neither the teacher nor the student knows the answer. (Agree with closest subject: student)
• Mistake 3: ❌ Everyone have finished their homework. ✅ Everyone has finished their homework. (Everyone is singular)
• Mistake 4: ❌ The team are playing well together. ✅ The team is playing well together. (Team as a unit = singular)
• Mistake 5: ❌ She don’t like coffee. ✅ She doesn’t like coffee. (Third-person singular needs doesn’t)

Quick Summary

• A singular subject needs a singular verb.
• A plural subject needs a plural verb.
• Ignore phrases like along with or as well as when finding the subject.
• Use singular verbs with each, every, everyone, nobody, someone.
• For or/nor, match the verb to the nearest subject.
• Collective nouns can be singular or plural depending on context.
• Expressions like half of agree with the noun after of.

Conclusion

Subject-verb agreement might seem tricky at first, but with a little practice, it becomes second nature.

Keep these rules handy, and your writing will be clearer and more professional.

FAQ

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

The most common mistake is when a prepositional phrase comes between the subject and verb. For example, in The box of chocolates are delicious, the subject is box (singular), so the verb should be is, not are. Always ignore the words in the prepositional phrase.

2. Do collective nouns always take a singular verb?

Not always. In American English, collective nouns (team, family, committee) usually take a singular verb when the group acts as one unit. In British English, they can take a plural verb when the members act individually. Example: The family is moving to London. (US) vs. The family are arguing about the move. (UK).

3. What verb do I use with each and every?

Always use a singular verb with each and every, even if they are followed by a plural noun. Example: Every student is required to bring a laptop. (Not are required.)

4. How do I handle subjects like news or mathematics?

Words like news, mathematics, physics, economics, and politics look plural but are treated as singular in English. Use a singular verb: The news is surprising. / Economics is a fascinating field.
