Rhaetic was written using two varieties of the
Etruscan alphabet: the Sanzeno and Magrè alphabets. They were almost identical except for the writing of a few characters. Generally, in the Sanzeno alphabet,
pi is written with two lines,
lambda and
upsilon are pointed down, and
heta uses two horizontal lines. In the Magrè alphabet, pi uses three lines, lambda and upsilon are pointed up, and heta uses three horizontal lines. Additionally,
alpha,
phi,
tau, and the letter for the dental affricate are written differently. Besides characters, the two alphabets also differ slightly in punctuation. Word separation is sometimes seen in Sanzeno texts, but never seen in Magrè texts. Magrè was more commonly used to write Rhaetic than Sanzeno. The vast majority of Sanzeno texts are from far northern Italy, and only from the 4th and 5th centuries BC. Magrè texts however have been found from northern Italy to southern Germany, and cover the entire known time Rhaetic was spoken. The origins of Rhaetic's alphabets are ultimately unknown, but they seem to have been adopted through
Venetic. The punctuation and the direction certain letters face in Magrè, as well as Magrè's use in close vicinity to Venetic, suggest some sort of relationship between them. Sanzeno, however, retains many traditional Etruscan writing traditions. Both alphabets use a unique letter for the dental affricate however, something that Etruscan's
zeta could have provided if Etruscan was the source of either of the Rhaetic alphabets. In Venetic however, zeta is rarely used, suggesting it as the more likely source of the Rhaetic alphabets. It is still unknown whether the two alphabets share a common origin or if they developed independently of each other, and to what degree if they did. As of April 2020, there are 389 total inscriptions listed in the
Thesaurus Inscriptionum Raeticarum's
corpus. Of these, only 112 have been positively identified as Rhaetic. 177 have only two characters or less, and many have not been transliterated. == Phonology ==
