Rhaetic or Raetic (ˈriːtᵻk), also known as Rhaetian, was a Tyrsenian language spoken in the ancient region of Rhaetia in the eastern Alps in pre-Roman and Roman times. It is documented by around 280 texts dated from the 5th up until the 1st century BC, which were found through northern Italy, southern Germany, eastern Switzerland, Slovenia and western Austria, in two variants of the Old Italic scripts. Rhaetic is largely accepted as being closely related to Etruscan.
The ancient Rhaetic language is not to be confused with the modern Romance languages of the same Alpine region, known as Rhaeto-Romance.
Tyrsenian languages
The German linguist Helmut Rix proposed in 1998 that Rhaetic, along with Etruscan, was a member of a language family he called Tyrrhenian, and which was possibly influenced by neighboring Indo-European languages. Robert S. P. Beekes likewise does not consider it Indo-European. Howard Hayes Scullard (1967), on the contrary, suggested it to be an Indo-European language, with links to Illyrian and Celtic. Nevertheless, most scholars now think that Rhaetic is closely related to Etruscan within the Tyrrhenian grouping.
Rix's Tyrsenian family is supported by a number of linguists such as Stefan Schumacher, Carlo De Simone, Norbert Oettinger, Simona Marchesini, and Rex E. Wallace. Common features between Etruscan, Rhaetic, and Lemnian have been observed in morphology, phonology, and syntax. On the other hand, few lexical correspondences are documented, at least partly due to the scanty number of Rhaetic and Lemnian texts and possibly to the early date at which the languages split. The Tyrsenian family (or Common Tyrrhenic) is often considered to be Paleo-European and to predate the arrival of Indo-European languages in southern Europe.
In 2004 L. Bouke van der Meer proposed that Rhaetic could have developed from Etruscan from around 900 BCE or even earlier, and no later than 700 BCE, since divergences are already present in the oldest Etruscan and Rhaetic inscriptions, such as in the grammatical voices of past tenses or in the endings of male gentilicia.
