This project aims at covering a whole domain of Catalan Sign Language (LSC) grammar that is still poorly understood for the most part or only partially addressed: reference. Under this very broad header we encompass the morphological, syntactic, semantic and pragmatic means that LSC has at its disposal in order to mainly talk about individuals, but also about times and worlds, for instance. The four areas of research to be tackled are: (i) the morphosyntax of Determiner Phrases; (ii) the pronominal system; (iii) quantification, and (iv) anaphoric chains in discourse.
