When two independent clauses are joined without the proper punctuation, it results in a run-on sentence. This structure occurs when sentences that could stand alone as complete thoughts are incorrectly connected, usually by just a conjunction or simply placed next to each other without any punctuation that would typically indicate their separation.

For example, if one were to say, “I enjoy reading I can finish a book in a day,” this sentence incorrectly combines two independent clauses without the appropriate conjunction or punctuation, such as a semicolon or period.

Understanding this concept is essential because proper sentence structure enhances clarity in writing. Recognizing and correcting run-on sentences helps to ensure that ideas are communicated effectively and that each independent clause is given the proper emphasis and separation they require.
