Tsakonian, or Tsaconian (also Tzakonian or Tsakonic; Greek: τσακώνικα; Tsakonian: τσακώνικα, α τσακώνικα γρούσσα), is a highly divergent modern variety of Greek, spoken in the Tsakonian region of the Peloponnese, Greece. Tsakonian derives from Doric Greek, being its only extant variant.[3] Although it is conventionally treated as a dialect of Greek,[4][5][6] some compendia treat it as a separate language.[7] Tsakonian is critically endangered, with only a few hundred, mostly elderly, fluent speakers left.[7] It is mutually unintelligible with Standard Modern Greek.
