What Are Sentence Types?

In essence, sentences are the building blocks of our language. They convey thoughts, feelings, questions, or commands. But did you know that sentences fall into four main categories based on their purpose? Recognizing these categories helps you craft more precise and engaging sentences.

Here’s a quick overview:

Sentence Type	Purpose	Typical End Punctuation	Example
Declarative	To make a statement or provide information	Period (.)	The sky is blue.
Interrogative	To ask a question	Question mark (?)	Are you coming to the party?
Imperative	To give a command or make a request	Period (.) or exclamation (!)	Please close the door.
Exclamatory	To express strong emotion or excitement	Exclamation mark (!)	What a beautiful view!

Now, let’s look at each sentence type in detail to truly understand their features, usage, and how to identify them in everyday writing.
