What is the concept of subject-verb agreement?

The concept of subject-verb agreement centers around the requirement that the subject of a sentence and the verb used must correspond in number. Specifically, this means that if the subject is singular, the verb should also be singular; conversely, if the subject is plural, the verb should match with a plural form. This grammatical rule ensures clarity and coherence in writing and speaking, making it easier for readers and listeners to understand the intended meaning of a sentence.

For example, in the sentence "The dog runs," "dog" is a singular subject and "runs" is the singular verb that agrees with it. Conversely, in "The dogs run," "dogs" is plural and requires the plural verb "run." Observing proper subject-verb agreement is crucial for clear communication in English.
