What is the subject of a sentence?

The subject of a sentence is fundamentally the person, place, thing, or idea that the sentence revolves around. It is what the sentence is describing or discussing. This definition encapsulates the essential role of the subject in sentence structure, as it serves as the main focus that conveys who or what is in action or being described. Understanding the subject helps in grasping the overall meaning of the sentence, as it establishes the context for the action or state conveyed by the verb.

In contrast, while the action being performed pertains to the predicate of a sentence, it does not define the subject itself. Similarly, the emotional content and specific details that follow the verb pertain to different components of the sentence structure and are not reflective of what the subject represents. Recognizing the subject allows for clearer comprehension and analysis of sentence construction and meaning in written and spoken language.
