Past research on the Sabellian languages has been devoted mainly to the phonetic and morphological features of these languages as elements for the reconstruction of the prehistoric stages of Latin. The present book aims at analysing the semantic, syntactic, and pragmatic features of a subset of grammatical terms, the demonstratives. It contains a thorough description of their synchronic behaviour, which permits both a comparison to the Latin data with new hypotheses on the epigraphic genres in Republican Italy and a reconstruction of the Italic origins of these terms based on typological principles. Neither the grammar of Sabellian nor the pragmatic scope of the Sabellian inscriptions should be considered a priori identical to their Latin comparanda.
