Subject-verb agreement is a fundamental rule in English grammar that states that the verb must agree with the subject in number and person. Therefore, it is essential to ensure that the subject and verb match in terms of number (singular or plural) and person (first, second, or third).
Here are some examples of subject-verb agreement in class 9:
1. Singular subject and singular verb:
Incorrect: The dog chase the cat.
Correct: The dog chases the cat.
In this sentence, the subject is singular (the dog), and therefore, the verb must also be singular (chases).
2. Plural subject and plural verb:
Incorrect: The boys am in the park.
Correct: The boys are in the park.
In this sentence, the subject is plural (the boys), and therefore, the verb must also be plural (are).
3. Compound subject:
Incorrect: Tom and Jerry walks to school.
Correct: Tom and Jerry walk to school.
In a compound subject, if both subjects are singular, the verb should be singular. If both subjects are plural, the verb should be plural.
4. Indefinite pronouns:
Incorrect: Someone have left their book on the table.
Correct: Someone has left his/her book on the table.
When the subject is an indefinite pronoun such as someone, everyone, anyone, nobody, etc., the verb should match the singular form.
5. Collective nouns:
Incorrect: The team are practicing for the match.
Correct: The team is practicing for the match.
When referring to a collective noun, such as team, committee, family, etc., the verb should be singular.
In conclusion, subject-verb agreement is a crucial rule in English grammar, and it is essential to ensure consistency in number and person between the subject and verb. By following these examples and rules, you can improve your writing and avoid common grammatical errors.
