1. A subject: This is who or what the sentence is about. It's usually a noun or pronoun.
2. A verb: This is the action or state of being of the subject.
Here are some examples:
* Subject: The cat | Verb: slept.
* Subject: She | Verb: laughed.
* Subject: The sun | Verb: is shining.
Additionally, a complete sentence must:
* Express a complete thought: It should be clear and understandable.
* Have correct grammar: It should follow the rules of sentence structure.
Let's look at some examples of incomplete sentences:
* The cat. (Missing a verb)
* Slept soundly. (Missing a subject)
* Because it was raining. (Not a complete thought)
Remember: A complete sentence is a powerful tool for clear communication.
