    Usage notes

    In modern usage, the form do not ... ( or don’t ... ) is preferred to ... not for all but a short list of verbs ( is/am/are/was/were, have/has/had, can/could, shall/should, will/would, may/might, need ):

    American usage tends to prefer don’t have or haven’t got to have not or haven’t, except when have is used as an auxiliary ( or in the idiom have-not ):

    The verb need is only directly negated when used as an auxiliary, and even this usage is rare in the US .

    The verb dare can sometimes be directly negated .
