    9.2 Modal verbs (cont'd..)


    Do also has dual function: as a principal verb and as an auxiliary verb. For instance:
    He does it.
    Here `does' is principal verb.
    He does not do it.
    Here does is auxiliary verb assisting the verb `do' to make it negative.

    do is also used to emphasize the action. Example:
    I do work for you.


    The same arguments are applied in case of verb to have also.
    I have a book.
    Here `have' is principal verb.
    I have done it.
    Here `have' is auxiliary verb.

    May, might

    As a principal verb it can express:

    1. permission:
      You may wear my shirt.
      He may phone me.
      The accused person may appeal to any court.
    2. possibility:

    3. He may lend the money.
      We may go to Bombay then.

    4. request: May I have your pen.
