("Can I have some juice?") "Could I...?" is polite/neutral, suitable for most situations. ("Could I borrow a pen?") "May I...?" is formal/polite, often used with superiors or strangers. ("May I see your ticket, please?") 2. Example responses: "I’m sorry, but you can’t copy my homework." / "No, I’m afraid you may not copy it." 3. Example: "You mustn’t run in the corridors." / "You can’t eat in the classroom." Both express prohibition ("not allowed to"). "Mustn’t" often emphasizes the rule/authority, "can’t" states impossibility due to rules. Meaning is very similar here. 4. "Might" is less common than "could" or "may" for permission requests today; it sounds very formal or hesitant. Someone might use it to sound extremely polite or cautious. A more common alternative is "Could I leave early today?" or "May I leave early today?"
