What is simple subject?</h3>
A single noun or pronoun that is joined to a verb is a simple subject. The simple subject usually comes before the verb in sentences. The single, unaltered person, place, thing, or idea makes up the simple subject, but the whole subject may also include modifiers (adjectives, relative clauses, and prepositional phrases).
The subject and the predicate are the two parts of every sentence. A sentence's topic determines who or what it is about. The area of the sentence where the verb is located is referred to as the predicate.
