What role does a subject typically play in a sentence?

The role of a subject in a sentence is to perform the action of the verb. In English grammar, the subject is typically a noun or a pronoun that indicates who or what is being discussed or who is doing the action. For example, in the sentence "The dog barks," "The dog" is the subject because it is the one performing the action of barking.

Understanding this function is crucial as it emphasizes the relationship between the subject and verb within the structure of a sentence, enabling clear communication of ideas. Recognizing the subject helps in understanding the overall meaning and grammatical correctness of sentences.
