do you know any languages that distinguish between various sorts of the first person in plural i.e. we ? I can think about several different ones but I never heard of a language whose grammar would distinguish between them:
1) WE = ME + YOU i.e. the person(s) I am talking to
2a) WE = ME + the persons on whose behalf I am speaking and who are present
2b) WE = ME + the persons on whose behalf I am speaking and who are absent
3) WE = ME + YOU + THEM
In languages that offer a variety of pronouns that are related to levels of formality/politeness some of the above distinction could be delivered between lines - but are there languages that can do the same by simply using separate personal pronouns?
