Subject-verb agreement is a fundamental aspect of grammar that every language learner must grasp to communicate effectively and accurately. Although the concept may seem simple, many learners continue to make mistakes in their writing and speech. This article aims to provide helpful tips and strategies for mastering subject-verb agreement and avoiding common errors. By understanding the basic rules and practicing them consistently, learners can significantly improve their language proficiency and boost their confidence in both written and spoken communication.

Understanding the Basics of Subject-Verb Agreement


Subject-verb agreement refers to the grammatical rule that requires the verb in a sentence to agree in number with its subject. In other words, singular subjects require singular verb forms, while plural subjects require plural verb forms.

The Core Rule

The core rule of subject-verb agreement is straightforward: singular subjects take singular verbs, and plural subjects take plural verbs. For example:

  • The cat is sleeping. (singular subject and verb)
  • The cats are sleeping. (plural subject and verb)

It’s important to recognize the difference between singular and plural verb forms and to practice using them correctly with their corresponding subjects.

Identifying Singular and Plural Subjects

One of the first steps to mastering subject-verb agreement is learning to identify singular and plural subjects in sentences. Singular subjects refer to one person, place, thing, or idea, while plural subjects refer to more than one.

Examples of singular subjects:

  • A dog
  • The teacher
  • My friend

Examples of plural subjects:

  • Dogs
  • The teachers
  • My friends

When determining the subject’s number, pay attention to the noun and any modifiers, such as articles or quantifiers, that come before it. For example:

  • A dog is barking. (singular subject)
  • Some dogs are barking. (plural subject)

In the first example, the indefinite article “a” signals that the subject is singular. In the second example, the quantifier “some” indicates that the subject is plural.

Common Mistakes and How to Avoid Them

Mistake: Using Plural Verbs with Singular Subjects

One of the most common errors in subject-verb agreement is using plural verbs with singular subjects. This mistake often occurs when the subject is a collective noun, such as “team” or “family,” which refers to a group of people or things acting as a unit.


  • The team are playing well. (incorrect)
  • The team is playing well. (correct)

To avoid this error, remember that collective nouns are singular, even though they refer to a group of people or things. Use a singular verb form with these nouns.

Mistake: Failing to Match the Verb to the Subject

Another common mistake is failing to match the verb to the subject in terms of number. This error often occurs when the subject is separated from the verb by a long or complicated phrase.


  • The book on the shelf, along with the pen and notebook, are mine. (incorrect)
  • The book on the shelf, along with the pen and notebook, is mine. (correct)

To avoid this error, identify the subject and its number first, then choose the appropriate verb form that matches it. Ignore any modifiers or phrases that come between the subject and the verb.

Mistake: Overlooking Irregular Verb Forms

Irregular verbs are verbs that do not follow the regular pattern of adding “-s” or “-es” to the base form to make the third-person singular. For example, the verb “to be” has the irregular third-person singular form “is.”


  • She speak English very well. (incorrect)
  • She speaks English very well. (correct)

To avoid this error, learn the irregular verb forms and practice using them correctly with their corresponding singular subjects.

Tips for Practicing Subject-Verb Agreement

Read and Listen to Authentic Materials

Reading and listening to authentic materials, such as books, articles, and podcasts, can help learners develop an intuitive understanding of subject-verb agreement in context. Pay attention to how native speakers use verb forms with different subjects, and try to identify any patterns or rules.

Use Grammar Exercises

Using grammar exercises, such as worksheets or online quizzes, can help learners practice identifying singular and plural subjects and choosing the appropriate verb form. These exercises can also help learners identify common mistakes and learn how to correct them.

Practice Writing and Speaking

Regular practice writing and speaking with correct subject-verb agreement can help learners reinforce their understanding of the rules and develop fluency. Seek feedback from a language teacher or native speaker to identify any errors and areas for improvement.


Mastering subject-verb agreement is a critical skill for language learners seeking to communicate accurately and effectively. By understanding the basic rules, identifying singular and plural subjects, avoiding common mistakes, and practicing regularly, learners can significantly improve their language proficiency and confidence. Remember to read and listen to authentic materials, use grammar exercises, and practice writing and speaking to reinforce your understanding and develop fluency.
