The auxiliary verbs are those that help in the conjugation of other verbs and that's why they get that name.
They join the main verb in the formation of compound tenses and verbal locutions.
The main auxiliary verbs in Portuguese are to be, to be, to have and to have.
Classification
Alongside the main auxiliary verbs (to be, to be, to have, to have), the verbs "to go" and "to walk" are also classified as tense auxiliary verbs.
In this case, the verb inflection only occurs with the auxiliary verb, while the main verb appears in the participle (-ado, -edo, -ido), infinity (-ar, -er, ir) or gerund (-ando, -endo, -going).
Example: we will eat while they don't arrive.
There are also the modal auxiliary verbs which indicate desire, intention and possibility, for example: wanting, having to, being able to, achieving, intending, arriving, trying, having to, having to.
In this case, the main verb appears in the gerund (-ando, -endo, -indo) or in the infinitive (-ar, -er, -ir).
Example: Students want to learn math.
In addition to these classifications, we also have the curative auxiliary verbs, also called “aspectuals”.
They indicate action, continuity and repetition of the verbal action, adding meaning to the main verb. They are: continue, start, get used to, go, come, return, return, walk, leave, end.
In this case, the main verb appears in the gerund (-ando, -endo, -indo) or in the infinitive (-ar, -er, -ir).
Example: Joel keep listening the same song.
Formation of Compound Times
Compound tenses are made up of an auxiliary and a main verb.
At formation of compound times the most used auxiliary verbs are the to have it's the be.
Generally, the main verb appears in the participle (-ado, -edo, -ido), for example:
Luis Felipe she had passed by her mother's store when the accident happened.
Bridle would have spoken with him before if she didn't have an appointment.
