Parts of a sentence

A sentence has two parts :

1. The subject is the person(s) or the thing(s) we are talking about. It may consist of one word or many words.
2. The predicate tells us something about the subject. It may also consist of one word or many words.

   Subject	Predicate

In some imperative sentences, the subject may not be stated. It is understood.
Complete your work. (You is the hidden subject.)
