Each sentence has two parts: a subject and a predicate.
The subject of a sentence is the person, thing, or idea that the sentence is about.
The predicate of a sentence gives information about the subject.

We can divide the sentence into two parts, like this: The gray cat / chased the tiny mouse.
Subject: The gray cat
The sentence is about the gray cat. The gray cat is the subject of the sentence.
Predicate: chased a tiny mouse.
The predicate tells what the subject is doing. Chased a tiny mouse tells more about the gray cat.
The subject is always a noun or a pronoun.
The predicate always begins with a verb.
