Subject - Predicate

• When we have a sentence in English, it must have a subject and a predicate.

• Subject : Subject of a sentence is the main thing, person or place about what we are talking in the sentence. It is what the sentence is about.  

          For example,  
         - My father is a teacher. (Subject - My father) 
         - Each one of us is interested in this discussion. (Subject -  Each one of us)  

• Predicate: The predicate usually follows the subject, it is something that is told about the subject. It tells us about subject or gives us information about the subject that what the subject is/does/has.

          For example,  

           -  My father is a teacher. ( Predicate - is a teacher)

      - Each one of us is interested in this discussion. ( Predicate- is interested in this discussion)

• She is my friend.
• It's raining.
• Rimjim sings a song.
• My brother Vipul gave me a gift yesterday.
• Rosy and Nancy went to the market yesterday.
• Here comes the bus.   

Words in red are subjects: words in blue are predicates.

• Subjects and predicates can be either simple, complete or compound.

• Simple subject - Only a noun or pronoun
• Simple predicate - a complete verb 

            - e.g : She sings a song.

• Complete subject : Noun or pronoun plus modifiers
• Complete predicate : A complete verb plus modifiers

            - e.g. : The black cat ran away in the dark. ( the black cat- complete subject; ran away   in the dark- complete predicate.)

• Compound subject: Two or more subjects joined by a conjunction.
• Compound predicate: Two or more predicates with the same subject

              - e.g : She and her father were dancing sweetly and gracefully.     

(She and her father- compound subject, was dancing nicely and lovingly-Compound predicate)

• Does the subject always come before the predicate?

• It is not always necessary that the subject comes first in the sentence, it can be in between the predicates or sometime last in the sentence as well.
• e.g.  Mr Shah reached here just now.
• Just now, he reached here.
• There are many chairs in this room.
• Here comes Mr Shah !
• Keep in Mind: In imperative sentences we don't have a visible subject.
• E.g. : Switch off the fan please.
• In these kind of sentences subject is second person - You.
