What constitutes the core meaning of a subject in a sentence?

The core meaning of a subject in a sentence is best represented by the predicate. The predicate provides information about what the subject does or is, effectively forming the crucial part of the sentence that communicates the action or state of being associated with the subject. While the subject indicates who or what the sentence is about, the predicate completes the thought by adding more detail regarding that subject.

In contrast, while the verb is an essential part of the predicate, it does not encompass the entire predicate, which may also include other components such as direct or indirect objects and modifiers. The antecedent refers to the noun that a pronoun replaces or refers back to, which does not capture the meaning of the entire sentence. The object serves as a complement to the verb in relation to the subject but does not represent the overall meaning of the sentence structure. Thus, the predicate is the integral part that delivers the complete idea being expressed about the subject.
