Understanding how to ask for, give, and deny permission is one of the most practical skills you can develop in English. The modal verb can — along with its negative form can't and the more formal alternative may — gives you the tools to handle everyday situations with confidence, from classroom requests to workplace conversations.

¿Cómo se pide permiso con can y may? [0:29]

When you want to ask for permission, you place can or may before the subject pronoun, followed by the base form of the verb. The structure is simple: Can/May + subject + verb?

Here are some examples directly from the lesson:

Can I go now? / May I go now?
Can we go to the game tomorrow? / May we go to the game tomorrow?
Can I go to the bathroom, please? — the classic school question.
Can they go home early today?

Notice that may is used in more formal contexts [0:52]. Both options are completely correct, but choosing one over the other depends on the level of formality you need. In a professional email, may sounds more polished; among friends, can is perfectly natural.

¿Cómo se da permiso en inglés? [1:29]

Giving permission follows the same logic but in an affirmative response. You confirm with can or may plus the action:

Yes, you can go now.
Of course, you can go to the game tomorrow.
Yes, you may go to the bathroom.
Sure, they can go home early today.

Words like of course and sure add a friendly, encouraging tone to your answer. They signal that permission is granted willingly, not reluctantly.

¿Qué diferencia hay entre can y may al dar permiso?

The difference is purely about register. In casual speech, can dominates. In formal settings — a courtroom, a business meeting, or an academic environment — may is the preferred choice. Both carry the same meaning; only the tone changes.

¿Cómo se niega permiso con can't y may not? [2:07]

To deny permission, replace can with the contraction can't (cannot). This is the most common way to refuse a request in spoken English:

I'm sorry, but you can't go now.
Unfortunately, you can't go to the game tomorrow.
No, you can't go to the bathroom.
They can't go home early today.

For a more formal refusal, use may not instead [2:41]. For instance: I'm sorry, you may not go now. Note that may not is never contracted in standard English — there is no "mayn't" in modern usage.

¿Qué expresiones suavizan una negativa?

Adding phrases like I'm sorry, but… or unfortunately softens the denial and makes it sound more polite. Compare these two sentences:

You can't go. — direct and blunt.
I'm sorry, but you can't go. — respectful and considerate.

This small addition makes a big difference in real-life communication, especially in professional or educational environments.

¿Cómo practicar estas estructuras?

The best way to internalize these patterns is to write your own examples [2:56]. Try creating two sentences for each function:

Two questions asking for permission.
Two statements giving permission.
Two statements denying permission.

Think about real scenarios: asking your boss to leave early, allowing a friend to borrow something, or telling someone they cannot park in a certain spot. The more relevant the context, the faster you will remember the structure.

Share your examples in the comments — practicing with real sentences and getting feedback is the fastest path to fluency.
