The determiner det~jet~thet has been considered a definite article for the purposes of discussing this feature. Similarly to the German article, it simultaneously fills a slot in the demonstrative paradigm and is used as a text-deictic demonstrative; therefore it is considered identical to a demonstrative (see also Feature 28 "Definite articles"). It does not co-occur with another adnominal demonstrative form; however it may co-occur with an adverbial demonstrative ('here'/'there') in adnominal position. As it has no spatial deictic value, it is glossed as DEM in the examples.
