How to Use the Sentence Completeness Checklist
Enter a sentence and this tool checks whether it has a subject (a pronoun or capitalized noun at the start), a verb (an action or linking word), and an object or complement (words following the verb), showing the results in a checklist. Since intransitive sentences like "She smiled" don't require an object, that row is shown for reference rather than as a strict requirement — a sentence is considered structurally complete once a subject and verb are both found. Use it to review a writing draft or when studying English sentence structure.
This is a lightweight checker based on word patterns like capitalization, common auxiliary verbs, and word position — it doesn't check spelling or detailed grammar. If you enter multiple sentences at once, they're treated as a single block, so enter one sentence at a time for the most accurate result.
