This study identifies and describes constituents, patterns and distribution of the system –or systems- of demonstratives of a representative selection of early Greek dialects, namely the “Arcado-Cyprian” group: Arcadian and Cyprian, including a short analysis of Pamphylian as well as a discussion of the particle νι/νυ and a brief note on Mycenaean; the “Aeolic” group: Lesbian, Boeotian and Thessalian; and a selection of West Greek dialects, including both “Doric” and “Northwest Greek” dialects: Elean, Cretan, Laconian, Cyrenaean and Theran. It also examines, describes and compares the syntactic functions and, where possible, pragmatic uses of the series of demonstratives in operation in the selected dialects, providing a classification capable of accounting for all uses cross-dialectically, as well as a succinct account of the evolution of the system of demonstratives from Indo-European to “Ancient Greek”. Additionally, it offers a glimpse of the way in which deixis and anaphora seem to have worked in early Greek dialectal inscriptions, addressing the issue of defining demonstrative pronouns, as well as deixis and anaphora in general terms. Finally, this thesis provides the basis for a cross-dialectal comparison of the structure and operation of the different systems of demonstratives, and corrects some general misconceptions about the scope, usage and inter-dialectal connections of some series of demonstratives, particularly with regard to Arcadian and Cyprian. The results of such a study might contribute towards the discussion of the classification and history of the evolution of early Greek dialects.
