The present chapter outlines the main lexical and morphological features of demonstrative pronouns, adnominals, and adverbs in the main Sardinian dialects. It also provides a more detailed analysis of the syntax, semantics, and pragmatics of the above-mentioned demonstratives in Campidanese. The research is developed on the basis of some new data, examined in a recent theoretical framework. As is wellknown, the Sardinian deictic system belongs to a three-term type: the analysis conducted here allows for a more precise description of the functional properties of the system.
