Look at the following sentences :
Ram sings.
The dog barks.
His work is done,
His name is known.
A clever boy will act thus.
My brother has gone.
Each of the above sentences may be divided into two parts, thus:
Subject and Predicate.
The first parts denote the persons or things about whom or which something is said. They are called 'Subject'.
The subject is a word, or a group or words, that denotes the person or thing about whom or which something is said. It must be a noun or a noun equivalent, and may consist of any number of words.
The second parts denote what are said about the subjects. They are called 'Predicate'.
The Predicate is a word, or a group of words, that denotes what is said about the subject. It must contain at least a finite verb, expressed or understood.
The Subject is often understood in some sentences, especially in Imperative ones. Thus,
Go there = You go there.
Sit down =You sit down.
In analysing such sentences, the subject has to be supplied.
