1. Declarative Sentence: States a fact or opinion. These are the most common type of sentence.
* Example: "The sun is shining."
2. Interrogative Sentence: Asks a question.
* Example: "Are you going to the store?"
3. Imperative Sentence: Gives a command or makes a request.
* Example: "Close the door."
4. Exclamatory Sentence: Expresses strong emotion.
* Example: "That was amazing!"
A fifth type, often considered a subcategory of the above, is the Exclamatory Interrogative Sentence. These sentences use question marks to express strong emotion, but are not actually asking a question.
* Example: "Did you see that amazing sunset?!" (Not actually asking if you saw it, but expressing how amazing it was).
It's important to note that there are other ways to classify sentences, such as by their purpose or by their grammatical structure. However, these four (or five, including the exclamatory interrogative) are the most common and widely accepted classifications of simple sentences.
