The present study undertakes a comparative investigation of the dialects of Thassos and Lesbos, systematically examining both shared and distinctive linguistic features across phonology, morphology, morphosyntax, and the lexicon. Based on primary ethnographic data and contemporary linguistic methodologies, the analysis demonstrates that, although the two varieties belong to the Northeastern Aegean dialectal continuum, they display both substantial similarities and significant divergences shaped by historical and sociolinguistic factors. These differences reflect the geopolitical position of each island: Thassos emerges as a more conservative enclave due to relative isolation, whereas Lesbos functions as a site of linguistic fusion shaped by sustained contact with Asia Minor populations. The study thus underscores the importance of comparative dialectology for understanding the dynamics of insular linguistic systems within the Northeastern Greek-speaking territory.
