    I think 'do' is an auxiliary verb rather than a full verb there.

    But I see this:

    do
    auxiliary verb
    used instead of repeating a verb that has already been used

    'Will Kay come?' 'She may do.'

    ------------
    In this sentence 'may' is a modal verb and 'do' is used to replace the verb 'come'.

    So are there two modal verbs in this sentence ('may' and 'do')?
    Is a contradiction between this sentence and what Piscean said (We don't replace a verb with DO when it follows a modal)?

    Could you please help me?

    Re: I can eat more than you can eat.

    That's not very natural. Try:

    A: Will Kay come?
    B: She might.

    I think She may do is common in conversational British English.

    (Update)

    OK, now I know that DO is an auxiliary verb, but that it is not a modal auxiliary verb.

    (Question
    )
    Is a contradiction between this sentence and what Piscean said (We don't replace a verb with DO when it follows a modal)?

    I am confused. I don't know whether We can replace a verb with DO when it follows a modal.

    In conversational British English maybe 'do' can replace a verb although the verb follows a modal verb.

    Am I right?

    (Why do I post the same question there? Because I don't get an answer.)
