Functionally, sentences are of mainly four types:
- Declarative sentence
- Imperative sentence
- Interrogative sentence, and
- Exclamatory sentence
Declarative sentence:
An assertive sentence (declarative sentence) simply expresses an opinion/feeling, or makes a statement, or describes things. In other words, it declares something. This type of sentence ends with a period (i.e., a full-stop).
Examples:
- I want to be a good cricketer. (a statement)
- I am very happy today. (a feeling)
Imperative sentence:
We use an imperative sentence to make a request or to give a command. Imperative sentences usually end with a period (i.e., a full stop), but under certain circumstances, it can end with a note of exclamation (i.e., exclamation mark).
Examples:
- Please sit down.
- I need you to sit down now!
Interrogative sentence:
An interrogative sentence asks a question. Interrogative sentences must end with a note of interrogation (i.e., question mark)
Examples:
- When are you going to submit your assignment?
- Do you know him?
Exclamatory sentence.
An exclamatory sentence expresses overflow of emotions. These emotions can be of happiness, wonder, sorrow, anger, etc.
Examples:
- What a day it was!
- I cannot believe he would do that!
