The term Taraskath may refer both to a people and a language.
The Taraskath (self-appelation generally used in English and other foreign languages, also called Tarathians - ТараΘийцы by the Ros) are the native people of Taraskovya, who inhabited what is now the Sisgardian Taraskovya dozens of thousands of years before the coming of of the Slavs.
Until the year 44’215 Before Strife and the unification of the various Taraskath tribes and city-states by Lord Uidath Karetsah, there was no single Taraskath nation or ethnos as such. Dakathian and Cardinian Taraskath spoke different slightly related languages and had differing cultures. Lord Uidath himself a Cardinian, this branch of the Taraskath culture came to predominate and slowly replaced the largely independent Dakathian culture.
The Taraskath language is an ancestral language which has known many a transformation throughout history. Manuscripts dating from dozens of millenia ago indicate that the first Dakathian and Cardinian dialects were mostly hissing tongues, revolved around a multiple of hissing consonnants and rare vowels. After the absorbtion of the Amalori, Kethari and Sethari peoples, the Taraskath language enriched itself and eventually became the modern High Taraskath: a language mixing hissing sounds with melodic syllables. In some areas of Dakathia, older and more hissing dialects of Taraskath are spoken.
The writing system is alphabetic, even if two scripts exist: the runic and the calligraphic scripts. The former is the "initial" script as used by the ancient Taraskath, with some additions. The calligraphic script was taken from the Amalori language and is used as a high flown variant, for particularly important letters and registers.
