Query: What language do most historians agree upon where the Greek names for the British Isles came from?
Context: Strabo used Βρεττανική (Brettanike), and Marcian of Heraclea, in his Periplus maris exteri, used αἱ Πρεττανικαί νῆσοι (the Prettanic Isles) to refer to the islands. Historians today, though not in absolute agreement, largely agree that these Greek and Latin names were probably drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί (Priteni or Pretani).
