What is Modal verbs?

Modal verbs (can, could, may, might, must, should, will, would) add a shade of meaning to the main verb: possibility, permission, obligation, advice or ability. They are always followed by the base verb, without to, and they do not change with the person: "She can swim", "He must go".

When to use it

Use them to ask permission ("May I come in?"), give advice ("You should rest"), express obligation ("You must wear a seatbelt"), talk about possibility ("It might rain") and make polite requests ("Could you help me?").

Common mistakes and tips for Spanish speakers

  • No to and no -s after a modal: "She can swim", never "She can to swim" or "She cans swim".
  • For questions, move the modal to the front: "Can you help?". Do is not used.
  • Must and have to are not always the same: in the negative, "mustn't" forbids while "don't have to" means it is not necessary.

Examples

  • You should see a doctor.

    Deberías ver a un médico.

  • Can I use your phone?

    ¿Puedo usar tu teléfono?

  • It might snow tonight.

    Podría nevar esta noche.

  • You mustn't park here.

    No debes estacionarte aquí.
