However in the negated and inverted clauses referred to above, it is used because the rules of English syntax permit these constructions only when an auxiliary is present. Apart from the verb "be", where, for example, "I am not" is used, it is not allowable (in Modern English) to add the negating word not to an ordinary finite lexical verb, as in *I know not – it can only be added to an auxiliary (or copular) verb, hence if there is no other auxiliary present when negation is required, the auxiliary do is used, to produce a form like I do not (don't) know. The same applies in clauses requiring inversion, including most questions – inversion must involve the subject and an auxiliary verb, so it is not possible to say *Know you him?; grammatical rules require Do you know him?Do-support is not used when there is already an auxiliary or copular verb present; nor is it used with non-finite verb forms (infinitives and participles) or with subjunctive forms.
