Subject and Predicate

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.

Subject	Predicate
Ram	sings.
The dog	barks.
His work	is done.
His name	is known.
A clever boy	will act thus.
My brother	has gone.

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.
