Rix's Tyrsenian family is supported by a number of linguists such as Stefan Schumacher, Carlo De Simone, Norbert Oettinger, Simona Marchesini, or 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.
