Simulate Language Conversations with Grammar Correction

The prompt establishes a clear role for the model — a corrective conversation partner — and sets explicit behavioral rules: reply in the target language, correct errors immediately, explain grammar simply, and offer alternatives. This constrains the model away from generic responses and toward structured pedagogical feedback. By anchoring the conversation to a concrete real-world scenario (ordering food, asking directions), the prompt keeps the vocabulary and grammar patterns contextually relevant and manageable for beginners, rather than drifting into abstract or advanced territory. The instruction to "suggest better ways to say things" goes beyond error correction and prompts the model to model fluent phrasing — a technique used in communicative language teaching where learners see correct forms in context rather than just being told what's wrong.
