A sentence is a grammatically independent unit of expression, made up of two essential parts called the Subject and the Predicate.
Every complete sentence has a subject and a predicate.
THE TWO MAIN PARTS OF A SENTENCE
The girl dances well
The girl is a subject and dances well is the predicate. If I come up to you and say "The girl", you know that is the subject about which I wish to talk. But I have said nothing about the subject. To make a sentence I must say something about the girl.
If I say "The girl dances well", I have expressed a complete thought and I have made a sentence.
In grammar the person or thing we speak about is called the subject. What we say about the subject is called the predicate.
Subjects tell the listener and the reader whom or what the sentence is about. The subject is that part of a sentence which names a person, thing, or idea
Every complete subject contains a simple subject. The simple subject, which is a noun or pronoun, is the most important word in the complete subject.

The predicate is that part of a sentence which tells something about the subject.
