A lot of words are defined in terms of "this", such as "here: this place". But "this" can be a pronoun ("is this your bag?") or determiner ("don't listen to this guy") or other things, all of which are kind of difficult to conceptually wrap your head around. I am wondering how the concept/function/word of "this" works in other languages.
- Do any languages completely do without a concept for "this" and "that"?
- Do any languages have more words than just this and that (that are relative to specifying a thing's distance)?
- Do any languages treat "this" as not a pronoun or determiner, but as a noun of some sort, or a verb of some sort, or an adjective (one of the 3 easy classes of words to conceptually grasp)?
If so, what are the key examples used to demonstrate this? Mainly I care about the 3rd point, but the other 2 would also be interesting cases to consider.
