The language has around more than 7 million of speakers, principally focused in Aŭstrasuno Tero and other parts of the Harda Archipelago. The language is combination of many sounds and vocabulary from Uletarephian languages into a simplified gramatical structure. Its main influences are Gaermanic and Romantish languages group, but also influenced by Proto-Tarephian, Hellasinian, Semitic and Slevic languages. The language origins are not completely clear, it is believed that its main roots come from an extinct country in Uletha, Nordanekonata in Aŭstro, that were spreaded by overseas travelers. The earliest document making a mention of the Aŭstro Language are in the foundational documents of Aŭstrasuno Tero, mainly in the document dated from 1450 En la serĉo de la libereco kaj liberigo de la sferoj. In the history of Aŭstrasuno Tero the language evolved and received many voice influences from native languages of Harda Archipelago, principally from Hesperico, Mahhalian and Semer comforming the three main and bigger dialects of the language. However, the dialects preserves the main gramatical and scripting rules of the original language.
