There are basically four types of sentences in English literature. They are:

• Declarative sentences
• Imperative sentences
• Exclamatory sentences
• Interrogative sentences

All the above mentioned sentences have many similarities but it's also a fact they can be identified with ease observing the differences they possess.

If you wonder what is a declarative sentence, here is an answer for you, ‘a declarative sentence is a sentence written in the form of a statement and not in exclamation, question or command form'. In English literature the most common type of sentences are declarative sentences. Through a declarative sentence is represented a fact. Besides sharing a fact or making a statement declarative sentence ends with a period. Given below are some examples of declarative sentences that will make you understand what is a declarative sentence, more clearly:

• He needs to go out
• Tropical rainforests are the biggest rainforests in the world
• Your uncle has come
• You are having your class in the evening
• The cap you gave me, couldn't fit on my head

It is clear from these examples that declarative sentences can be written as simple, complex or compound sentences. The basic purpose of the sentence is not at all affected by the structure of the sentence. But you must keep in mind that varying structure of a sentence keeps the .reader engaged and doesn't create boredom. Declarative sentences can be written simple, short and to the point without creating confusions. They also can be lengthy. Lengthy declarative sentence may contain objects that can be direct or indirect, prepositions and preposition objects. Whatever may be the length of a declarative sentence, do not get confused; remember that a declarative sentence always states something and does not interrogate or command or proclaim. Declarative sentences always sate facts.
