There are four types of sentences in English.

1. Declarative or assertive sentence
2. Exclamatory sentence
3. Imperative sentence
4. Interrogative sentence

Declarative sentence

A declarative sentence makes a simple statement.

Declarative sentences are of two types – affirmative sentences and negative sentences.

Examples are:

• She is my sister.
• He works at a family.
• Birds live in nests.
• We don’t have pets.
• I don’t know the answer.
• I didn’t do anything.

A declarative sentence begins with a capital letter and ends with a full stop.

Exclamatory sentence

An exclamatory sentence expresses a sudden emotion.

• How beautiful she is!
• What a lovely evening!
• How disgusting!

An exclamatory sentence begins with a capital letter and ends with an exclamation mark.

Imperative sentence

An imperative sentence expresses a command or request. Note that in imperative sentences, the subject is not usually mentioned.

• Come here. (Here the subject ‘you’ is not mentioned, but it is understood.)
• Keep quiet.
• Get me that file.
• Sit down.

Note that the subject of an imperative sentence is always the pronoun ‘you’.

Imperative sentences begin with a capital letter and ends with a full stop.

Interrogative sentence

An interrogative sentence asks a question.

• What is your name?
• Who is he?
• Where are you going?
• Are you coming with us?
• Does she work here?

An interrogative sentence begins with a capital letter and ends with a full stop.
