A "fragment" refers to a small part or piece that has broken away from a larger whole. In various contexts, such as literature or art, a fragment can represent an incomplete work or a portion of a larger narrative. For example, a fragment of a poem may evoke emotions or ideas without providing a complete story. In grammar, a fragment is an incomplete sentence that lacks a subject or a verb, making it unable to stand alone. For instance, "Running through the park" is a fragment because it does not express a complete thought. Understanding fragments is essential for clear communication in writing.
