Subject

Definition

In formal logic, a subject is the entity or individual that a statement or proposition is about. It serves as the focal point around which the information is conveyed, often being a noun or noun phrase that connects to the predicate, which describes something about the subject. The subject plays a crucial role in sentence structure and meaning, linking to how propositions are constructed and understood.
