Which form of speech relates to the person or thing that performs the action of the verb?

The correct answer is the term that identifies the core element of a sentence that performs the action of the verb. In grammar, the subject is the noun or pronoun that the sentence is about and is the entity that carries out the action of the verb. For example, in the sentence "The cat runs fast," "the cat" is the subject because it is the one performing the action of running.

Understanding this concept is essential for constructing clear and effective sentences, as it establishes who or what is involved in the action being described. Recognizing the subject helps in understanding the mechanics of sentence structure and aids in coherent writing, as it indicates who is responsible for the action being conveyed.
