Raetic or Rhaetic is a largely obscure language of antiquity, which used to be spoken in the province of Raetia, in the Eastern Alps, to the north and west of Venetic. It is sparsely attested, in inscriptions in various northern developments of the Etruscan alphabet, leaving room for much speculation on its ancestry. For a research history, see Schumacher (1992) and Schumacher (1998) and Morandi (1999) for editions of the inscriptions. All recent authorities have stressed a connection with Etruscan (Rix 1998, Schumacher 1998).
adjoining these (the Noricans) are the Raeti and Vindelici. All are divided into a number of states. The Raeti are believed to be people of Tuscan race driven out by the Gauls; their leader was named Raetus.
Based on this information and Raetian inscriptions it is clear that Raetic is related to Etruscan. Indeed in the usual classification the two are often grouped with Lemnian in the Aegean to form the wider Tyrsenian language family. This is itself usually taken to be an isolate family not demonstrably related to any other known language family - i.e. Raetic is not an Indo-European language.
Raetic became extinct by the 3rd century, after the speakers were assimilated and adopted Latin (in the south) and German (in the north). Many inscriptions are known, but most of them are only fairly repetitive and short, probably mostly votive texts. The name of the Venetic goddess Reitia has commonly been discerned in the Raetic finds, but the two names do not seem to be linked.
