Are there any examples of neopronouns for non-binary or third gender people being fully incorporated into a language's grammar?
Many non-binary people now request that new third person pronouns (neopronouns) be used to refer to them, for example xe or ze. These have not been widely used by English speakers yet, but it's still too early to say whether they might in the future.
Non-binary gender is a fairly recent concept for many people in western societies, but other societies have long had similar concepts, which anthropologists have termed third gender. Note that not all those who would identify with one of these would identify with the western terms transgender or non-binary gender.
Seeing as these third gender ideas have been around for thousands of years, I would like to know if there are any languages which have fully incorporated (ie, fully grammaticalised) neopronouns for non-binary or third gender people? I am specifically interested in pronouns that are used strictly for non-binary or third gender people, and not ones that are also used in a generic or indefinite manner (as the singular they is in English.)
