Arcadocypriot or southern Achaean was an ancient Greek dialect spoken in Arcadia in the central Peloponnese and in Cyprus. Its resemblance to Mycenaean Greek, as it is known from the Linear B corpus, suggests that Arcadocypriot is its descendant. Proto-Arcadocypriot (~1200 BC) is supposed to have been spoken by Achaeans in the Peloponnese before the arrival of Dorians; for this, it is also called southern Achaean.
