The Four Functions of Sentences 


All complete sentences contain a subject and verb, but all sentences function in the same way. In English all sentences can be classified according to one of four functions.

• Declarative Sentence
• Interrogative Sentence
• Imperative Sentence
• Exclamatory Sentence 

Declarative Sentence

 -  the most common sentence in English, used to express facts and opinions.

 -  it states an idea and ends with a period.

Interrogative Sentence

-  sentence asks a questions and ends with a question mark.

Imperative Sentence

-  demands or requests 

-  sentence gives an order or direction and ends with a exclamation mark.

-  expresses force or emotion, an exclamation mark rather than a period may be       placed at the end of the sentence.

Exclamatory Sentence

-  is always used to convey strong emotion and ends with an exclamation mark.

 The Nominative Case 

• Nominative Case is used when a personal pronoun acts in one of three ways. 

The Objective Case

• Objective pronouns are used for any kind of object in a sentence as well as for subjects of infinitives.

The Possessive Case

• Although errors are less common in the possessive case than they are in the other two cases, you should take care to use the possessive case before gerunds.

Pronoun Usage

Case
      is the form of noun or pronoun that indicates its uses in a sentence.
