(By Jeremy Collins and Jay Latarche): "Demonstratives are modifiers that can modify nouns (of any type and not just a restricted set such as location nouns) to mark position (e.g. deixis or reference within discourse). This doesn't have to be only Euclidean distance (meters, inches etc.), it could also be concerned with near or far in relation to the interlocutors (cf. Wolof). If the system of adnominal demonstratives includes an anaphoric demonstrative this does not count as a third distance."
