Subject-verb agreement is a crucial aspect of English grammar, which ensures that a sentence is well-constructed and makes sense. A sentence makes sense only if the subject and verb agree with each other in number, which means that a singular subject should have a singular verb, and a plural subject should have a plural verb.

To help you understand this concept better, here are some examples of subject-verb agreement:

1. Singular subject and singular verb:

– The dog barks at the mailman every morning.

– The teacher explains the lesson well.

– The book belongs to me.

2. Plural subject and plural verb:

– The dogs bark at the mailman every morning.

– The teachers explain the lesson well.

– The books belong to us.

3. Singular subject and plural verb:

– My sister and I love to travel.

– The CEO and the managers discuss the budget.

4. Plural subject and singular verb:

– The news is shocking.

– The police department investigates the crime.

In the first example, the singular subject “dog” has a singular verb “barks,” while in the second example, the plural subject “dogs” has a plural verb “bark.”

In the third example, the singular subjects “sister” and “I” are joined by the plural verb “love,” while in the fourth example, the plural subject “news” has a singular verb “is.”

It is important to note that some nouns that may seem plural, like “news,” “mathematics,” and “physics,” are treated as singular nouns.

In conclusion, subject-verb agreement is essential in writing clear and effective sentences. By following these examples, you can ensure that your sentences are grammatically correct and easy to understand.
