1. Subject: This is the person, place, thing, or idea that the sentence is about. It is the "who" or "what" that performs the action or is described.
2. Predicate: This part of the sentence tells what the subject does, is, or has. It contains the verb and any other information about the subject, such as objects, complements, and modifiers.
Example:
* Subject: The cat
* Predicate: slept on the rug.
Here, the subject is "cat" and the predicate is "slept on the rug". The predicate tells us what the subject did (slept) and where it slept (on the rug).
