The primary components of a sentence are the Subject and the Predicate. Every complete sentence must have both.
1. Subject
The Subject is the person, place, thing, or idea that is performing the action or being described in the sentence.
Simple Subject: The main noun or pronoun in the subject.
Example: The tall, lanky man is running.
2. Predicate
The Predicate is the part of the sentence that tells what the subject does, what is happening to the subject, or what the subject is like. It always contains the verb.
Simple Predicate (The Verb): The main verb or verb phrase that expresses the action or state of being.
Example: The car drove down the street. (drove)
