Many thanks for your reply and recommendation. It helps a lot. Your list of auxiliaries seems all right, but I would not include used to . I thought it’s just an idiom, but my grammar book and Longman dictionary tell me it’ is

I find that have to is most often called a semi-modal . It has the effect of a modal like must , but is conjugated like an ordinary verb. ( has to, have to, had to, ... ) I would certainly not call it an auxiliary verb with an infinitive, though
