You really need to calm down. I was speaking from the viewpoint of how Portuguese natives utilise language. I do not care nor am I an authority on the amount of honorifics any given language should or shouldn't use nor what the appropriate amount is. My statement applies only to how Portuguese natives have come to evolve and utilise our language and what is best suited for us.

Nowhere in Portugal is a four-part distinction of proximity relevant or utilised, insofar as its usage is perceived as archaic. This is not anecdotal, this is precisely how we are taught this language both in childhood immersion (where the fourth distinction is never present) and in school, where it is recommended for the studying of older texts and its understandings.

I have not found any formal study or investigation on why European Portuguese lost its second person plural, but most modern sources state simultaneously that it is archaic in most regions and it biggest historical expression is as a T-V treatment person and conjugation.

You can take your pretentious little behind elsewhere, since it is clearly not needed here, nor have you added anything of value to this conversation.
