The modal 'may' is often used for polite requests or permission in formal contexts. Example: 'May I use your phone?' or 'You may leave now.' In informal situations, 'can' is more common (e.g., 'Can I borrow your pen?'). 'Could' is also used for polite requests (e.g., 'Could you help me?'). Understanding these modals helps in appropriate communication in different settings.
