A relationship between Lemnian,
Raetic and
Etruscan, as a
Tyrsenian language family, has been proposed by German linguist
Helmut Rix due to close connections in vocabulary and grammar. For example, • Both Etruscan and Lemnian share two unique dative cases, type-I
*-si and type-II
*-ale, shown both on the Lemnos Stele (, 'for Hulaie', , 'for the Phocaean') and in inscriptions written in Etruscan (, 'to Aule', on the
Cippus Perusinus; as well as the inscription , meaning 'I was blessed for Laris Velchaina'); • A few lexical correspondences have been noted, such as Lemnian ('year') and Etruscan (genitive case); or Lemnian ('sixty') and Etruscan (genitive case), both sharing the same internal structure "number + decade suffix + inflectional ending" (Lemnian:
ši +
alχvi +
-s, Etruscan:
še +
alχl +
s); • They also share the genitive in
*-s and a simple past tense in
*-a-i (Etruscan - as in 'was' (< *amai); Lemnian - as in , meaning 'lived'). 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,
Raetic, 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 Raetic 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. According to Dutch historian Luuk De Ligt, the Lemnian language could have arrived in the
Aegean Sea during the
Late Bronze Age, when
Mycenaean rulers recruited groups of mercenaries from
Sicily,
Sardinia and various parts of the Italian peninsula. Scholars such as Norbert Oettinger, Michel Gras and Carlo De Simone think that Lemnian is the testimony of an Etruscan commercial settlement on the island that took place before 700 BC, not related to the Sea Peoples. After more than 90 years of archaeological excavations at Lemnos, nothing has been found that would support a migration from
Lemnos to
Etruria or to the
Alps where
Raetic was spoken. The indigenous inhabitants of Lemnos, also called in ancient times
Sinteis, were the
Sintians, a Thracian population. A 2021 archeogenetic analysis of Etruscan individuals concluded that the Etruscans were autochthonous and genetically similar to the Early Iron Age
Latins, and that the Etruscan language, and therefore the other languages of the Tyrrhenian family, may be a surviving language of the ones that were widespread in Europe from at least the Neolithic period before the arrival of the Indo-European languages, as already argued by German geneticist
Johannes Krause who concluded that it is likely that the Etruscan language (as well as
Basque,
Paleo-Sardinian and
Minoan) "developed on the continent in the course of the
Neolithic Revolution". The lack of recent Anatolian-related admixture and Iranian-related ancestry among the Etruscans, who genetically joined firmly to the European cluster, might also suggest that the presence of a handful of inscriptions found at Lemnos, in a language related to Etruscan and Raetic, "could represent population movements departing from the Italian peninsula". == Phonology ==
