This paper offers a case study of a definiteness split in a language in which three different types of nominal expressions are available for definite descriptions. The article contributes ample empirical data and comprises a close investigation of the patterns found in Reunion Creole (Réyoné), the language under study. Réyoné displays one kind of contrast also found in other languages which is frequently analyzed in terms of semantic vs. pragmatic definiteness (following Löbner 1985; 2011) or uniqueness vs. familiarity (following Schwarz 2009). What sets Réyoné apart from other languages though, is that it features a determiner that is dedicated to functional concepts. The language thereby distinguishes individual from functional concepts: individual concepts (the sun; the News) are exclusively expressed by bare noun phrases, while functional concepts – definite descriptions with functional head nouns (prefect of y; head of y), including a subtype of bridging reference, as well as compositionally created functional relations such as superlatives – are realized by lo-marked noun phrases. These facts offer strong support for Löbner’s theory. The paper also discusses demonstrative descriptions, which have already been reported to play a role in certain definiteness splits, and which are obligatory with sortal concepts in Réyoné. It is argued that demonstratives are pragmatic definites.
