Here's why:
* Independent clause: A group of words that contains a subject and a verb and expresses a complete thought.
* Sentence: A group of words that expresses a complete thought and is typically marked by punctuation.
Examples:
* One independent clause: "The cat sat on the mat."
* Multiple independent clauses: "The cat sat on the mat, and the dog chased its tail."
Important Note: Sentences can have multiple independent clauses, but they must be connected correctly using conjunctions or punctuation.
