Sentence structure, agreement, and the building blocks of clear sentences.

Fragment Frankie
Always leaves before finishing the.
Short lesson
- A sentence fragment is a group of words punctuated like a sentence but missing a subject, a main verb, or a complete thought.
- Fragments often start with words like because, when, or which, and lean on the sentence before them.
- Context matters: writers sometimes use an intentional fragment for emphasis or voice. In academic paragraphs, ask whether the fragment is a deliberate choice or an accident.
Practice 1 of 3
From a research paragraph: “Many students study in the hallway. Because the library closes at six.”
