Abstract
Effective communication in English relies heavily on the correct use of question forms, which function as essential tools for gathering information, maintaining interaction, and expressing politeness. English includes various question types Yes/No, WH-, indirect, and tag questions each serving distinct grammatical and pragmatic roles in both spoken and written discourse. Despite their importance, learners often struggle with mastering their structure, usage, and communicative function, particularly in differentiating between direct and indirect forms and applying appropriate intonation in tag questions. This study aims to provide a comprehensive grammatical and pragmatic analysis of major English question forms, enhancing learners’ understanding and communicative competence. Through qualitative descriptive methodology supported by linguistic corpora and scholarly grammar sources, the research identifies common structural rules and pragmatic features, demonstrating how indirect and tag questions contribute to polite and cooperative speech. Frequent learner errors such as incorrect word order in indirect questions and polarity mismatches in tag questions were also observed and analyzed. The study integrates grammatical analysis with corpus-based observations, offering authentic usage insights often lacking in prescriptive grammar instruction. The findings highlight the need for focused instruction and contextualized practice in teaching English question forms. Mastery of these forms not only improves grammatical accuracy but also enables more natural, polite, and socially effective communication, especially in diverse conversational settings.
