yaggy74“I understand that the primary Auxiliary verbs are be, have, do”
Yes, but they are not the only ones. In addition, auxiliaries can be divided into different categories.
Modals are also auxiliaries. Basically, modals cannot function as main verbs, whereas be, have and do can be used either as main verbs or as auxiliaries.
