This feature asks whether noun phrases with adnominal demonstratives (e.g. ‘this book’, ‘that house’) also contain a definite article. Noun phrases with an adnominal demonstrative are necessarily definite, so the definite article is redundant. Thus, some languages with an otherwise obligatory definite article (e.g. English) do not allow the article to occur when a demonstrative is present (*this the book), but others allow or require the definite article to co-occur with the demonstrative (e.g. Haitian Creole kandida sa a [candidate this the] ‘this candidate’). If a language allows both co-occurrence and non-co-occurrence with different demonstrative constructions, it has several different values.
