aux: auxiliary

An auxiliary of a clause is a non-main verb of the clause. In Italian the two main auxiliary verbs are form of essere (to be), avere (to have); in periphrastic tenses with the progressive form is used the verb stare instead. Modals are also marked as auxiliary (fare to do, sapere to know, volere to want, potere to can or dovere must).

stavano realizzando un serbatoio
aux(realizzando, stavano)

Note that the auxiliary verb used to construct the passive voice is not labeled aux but auxpass.
