Definition-

A declarative sentence is a sentence that makes a statement. This type of sentence typically ends with a period. 

For example, "The sun is shining."

While all declarative sentences make statements, not all statements are declarative.

 For example, an imperative sentence such as "Come to the party!" is not a declarative sentence, because it is not a statement. Rather, it is a command.

‍

Types of declarative sentences

There are four main types of declarative sentences

• simple
• compound
• complex
• compound-complex

‍

Examples and explanations

1. A simple declarative sentence contains a single independent clause. 

For example: The dog barked.

2. A compound declarative sentence contains two or more independent clauses. 

For example: The dog barked and the cat meowed.

3. A complex declarative sentence contains one independent clause and one or more dependent clauses. 

For example :The dog barked after the cat meowed.

4. A compound-complex declarative sentence contains two or more independent clauses and one or more dependent clauses. 

For example: The dog barked after the cat meowed, and then the bird tweeted.

More examples

• The sun is a star.
• I am happy.
• You are tall.
• She is my friend.
• Are you coming with us?
• The water is cold.

Notice that each of these sentences makes a claim or assertion. They are all declarative.

Conclusion

A declarative sentence is a sentence that states a fact or asks a question.
