Yes, you are correct. A sentence fragment fails to express a complete thought. It is a group of words that is punctuated like a complete sentence, but it does not contain a subject and a verb or does not express a complete idea. Sentence fragments are considered grammatically incorrect because they lack the necessary components to form a complete sentence.
