The title says it all. I would like to make an adjective relating to a place I am referring to via tie, much like I can create tiama from tiam in the fourth dimension. It does not need to be related to the word tie structurally.
A context where such word would be useful is, for example, when speaking of a place (country, subcontinent, area), to mention its culture or habits. The closest I can think of in English is "local" but Russian has a word which fits just perfectly: тамошний (там = there). That being one of the source languages of Esperanto, and actually using Esperanta way of creating an adjective from base words, gives me hope there's something more specific than loka.
