Different types of sentences help communicate your thoughts. We have listed explanations for each class below to make them easier to understand.


  1. Declarative Sentence

A declarative sentence is the most used sentence that conveys data. Any statement can be used, from the most important to the most insignificant.

Declarative sentences may be positive or neutral and can end with a full stop, period, or both.

Example 2: Yesterday, we did not play football.


  1. Interrogative Sentence

Interrogative sentences are designed to ask direct and specific questions to gain information. They are directed to a particular person or place and end with an interrogative sentence.

Conventional structure: (WH-word +) auxiliaryverb + subject + main verb+ object.

Example 1: Does anyone play football?

Example 2: Why do you not play soccer?


  1. Imperative Sentence


An imperative sentence instructs you or commands you to perform a task. It can be either an authoritative order, friendly advice or basic instruction. This type of sentence ends in a complete stop.

It can also end in an expletive mark to emphasize emotion. They don’t usually have a subject as YOU are considered the subject.

Conventional structure: base verb + object.

Example 2: Don’t touch it.


  1. Exclamatory Sentence

An exclamatory statement expresses strong emotion or surprise. Similar to imperative sentences, they provide information but end in an exclamation point instead of a full-stop.

Conventional arrangement 1: What (adjective + noun + subject and verb)

Example 1 What a beautiful lady you are!

Conventional Structure 2: How (+adjective/adverb + subject + verb
