A complete sentence has a subject and a verb or predicate. There are lots of different ways to make complete sentences, including using commas and semicolons to put together independent and dependent clauses. A clause is a group of words that has a subject and a verb. An independent clause can stand on its own. A dependent clause cannot. Take this sentence: “After we got under the covers, I told my little sister scary stories.” It has two clauses. “I told my little sister scary stories” is an independent clause.” “After we got under the covers” is a dependent clause.Sometimes a sentence has two independent clauses put together without proper punctuation. This is a mistake. It’s called a run-on sentence. You can think of it as a sentence that just keeps going, or just keeps running on. But remember, run-on sentences aren’t necessarily long sentences. Any sentence that contains two or more complete thoughts that need to be separated is a run-on.
Which of the following is a run-on sentence?
