Our Online English Grammar and Syntax Analyzer is a powerful yet beginner-friendly tool created for students, teachers, and language learners. It automatically analyzes sentences to identify parts of speech, clauses, predicates, and structural issues. Built on simplified, school-level grammar logic, the app is ideal for practice, learning, and teaching. Key Features 1. Parts of Speech Identification Instantly get a detailed list of words with Universal Part-of-Speech (UPOS) tags. Perfect for assignments, grammar drills, and understanding how words function within sentences. 2. Subject & Predicate Detection Automatically highlights the subject, the simple predicate (main verb), and the complete predicate (verb phrase) to help users grasp sentence structure. 3. Fragment Detection Identifies whether a sentence has both a subject and predicate (including linking verbs). Helps learners quickly recognize incomplete thoughts. 4. Run-on Sentence Detection Flags run-on sentences using a practical heuristic: multiple verbs without conjunctions or punctuation. A lightweight yet effective tool for training and exercises. 5. Clause Identification Distinguishes between independent and dependent clauses using Universal Dependencies (UD) labels. Essential for mastering sentence types and complex grammar structures. 6. Parallelism Check Checks if coordinated elements match in part of speech. Highlights mismatches, guiding learners to correct parallelism errors in writing. 7. Punctuation Validation Ensures every sentence ends with correct punctuation (., !, or ?), reinforcing complete and grammatically correct writing habits.
