Something neat about my conlang, Hip’alŭk’, is how it handles demonstratives (e.g., “this” & “that”). Demonstratives have both a three-way distinction between persons (speaker, addressee, and both) and a three-way distinction between distances (near, slightly far, and far).

This results in 9 different demonstratives (that I haven’t nailed down words for yet):

meoproximal DEM.PROX.1 — “this near me”
tuoproximal DEM.PROX.2 — “that near you”
omniproximal DEM.PROX.1+2 — “that near us both”
meomesial DEM.MES.1 — “that slightly far from me”
tuomesial DEM.MES.1 — “that slightly far from you”
omnimesial DEM.MES.1+2 — “that slightly far from us both”
meodistal DEM.DIST.1 — “that far from me”
tuodistal DEM.DIST.2 — “that far from you”
omnidistal DEM.DIST.1+2 — “that far from us both”
