From Middle English not, nat, variant of noght, naht (“not, nothing”), from Old English *nōht, nāht (“nought, nothing”), short for nōwiht, nāwiht (“nothing”, literally “not anything”), corresponding to ne (“not”) + ōwiht, āwiht (“anything”), corresponding to ā (“ever, always”) + wiht (“thing, creature”). Cognate with Scots nat, naucht (“not”), Saterland Frisian nit (“not”), West Frisian net (“not”), Dutch niet (“not”), German nicht (“not”). Compare nought, naught and aught. More at no, wight, whit.

In modern usage, do-support requires that 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, must, need, ought):
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, especially in the US.
The verb dare can sometimes be directly negated.
The verb do, as a main verb, takes do not.
In the imperative, all verbs, including be, take do not.
In the infinitive, verbs must be negated directly. In this case not cannot appear after the verb; some authorities recommend placing it before to to avoid a split infinitive, but for most speakers the forms not to do and to not do are more or less interchangeable, with the latter being mostly informal.
