1. Subject: This is the part of the sentence that tells us who or what is doing the action. It's the person, place, or thing that the sentence is about.
2. Predicate: This is the part of the sentence that tells us what the subject is doing or being. It contains the verb and any other information about the action or state of being.
Example:
* The cat (subject) sat on the mat (predicate).
Here, "the cat" is the subject, and "sat on the mat" is the predicate.
Note:
* Some sentences may have more complex structures, with multiple clauses or phrases.
* A complete sentence must have a subject and a predicate to express a complete thought.
