Here are some examples:
* The sky is blue.
* I love to eat pizza.
* The cat sat on the mat.
Important Note: While a period is the most common punctuation for declarative sentences, there are some rare exceptions:
* Interrogative sentences, which ask a question, end with a question mark (?).
* Exclamatory sentences, which express strong emotion, end with an exclamation point (!).
Let me know if you'd like more examples or have any other questions!
