In Taruven, the demonstrative is simply a noun. It may take all the noun-suffixes, but it can only be prefixed with ï-, ë- and aì-.
ry covers the meaning of both English this and that:
ry gav
gav ry
this/that dog
ty covers the meaning of English that better than it does this; it need only be used when the hidden, obstructed or unknown nature is essential:
ty gav
gav ty
that (unseen, hypothetical) dog
ty bren
bren ty
that car that once existed or someday will exist
(Only one of the possible word-orders are shown per example.)
ryuš
that below
ryašen
those behind
ryal
that inside
ryvunveneð ū
