Carantanian is a reconstructed Western South Slavic language, heavily based on the Freising manuscripts, the earliest known writings of the region.
The Carantanian language was created by the linguists of the South Slavic Academy of Science and Arts (JAZU), specifically in the one in Celovec. In this place, numerous Slavic linguists gathered, ranging from Croatian, Carantanian over Czechian and Balatonian and to Polish and Ruthenian as well.
The Carantanian language consists of 7 grammatical cases (Nominative, genitive, accusative, vocative, locative and instrumental) with examples shown in the table below. Grammatical cases affect nouns, pronouns and adjectives.
