Before entering vehemently into the subject that is now evident, it is worth remembering some details that will lead us to a more effective understanding. In this sense, let us remember that the personal pronouns of the straight case are manifested as follows: I, YOU, HE/SHE, WE, YOU, THEM/THEM.
According to this notion, it is also feasible that we recall two important grammatical parts, now demarcated by morphology and syntax. The latter, in turn, deals with the study of the functions performed by a given word, in view of a specific prayer context; and that one, has an objective that is guided by the study of the grammatical classes inherent to that same word.
In view of these assumptions, it is worth mentioning that when it comes to morphology, this one conceives them as being pronouns. However, given the syntax, which functions would they occupy? According to our studies, you will notice that they manifest themselves in different ways, as we can see below:
# Subject:
They they are good students.
We we study a lot.
# Subject's predicate:
the winners were we.
The advisor is Is it over there.
# Vocative:
Ó you, where have you been that you do not answer me?
Hey, you, you always listen to me, why did you abandon me?
