Old Catentiem

Old Catentiem, the genitive form of the neuter of Catentia, itself a mutated form of catenia meaning flatlands, known in the language as Catentien Legnen and occasionally as Catentēo Legne was a language spoken in ???. It was descended from Proto-~ and, more distantly, from Proto-??. Through these languages, it was related to Ancient Tarelion and other tongues.

Nounal
Old Catentiem nouns declined for five cases, which were nominative (used to denote the subject of a verb or the object of a predicate), accusative (used to denote the object of a verb or with certain prepositions), genitive (used to denote a relationship between nouns, such as for possession, in the genitive of the whole or for forming adjectives), dative (used to denote indirect objects) and ablative (used to denote general motion away from or towards something, with certain prepositions, for representing the time from which something took place and to represent means). Old Catentiem nouns also declined for three genders, masculine, feminine and neuter, with gender being an innate quality of every noun. Only a few nouns (generally occupations, people and animals) could take multiple genders. In addition to this, there were two separate noun declensions, marked by their different nominative endings, -o/-a/-e and -oia/-eio. Drawing from a mixture of analogy and regularisation, Old Catentiem underwent a remarkable process of declension expansion, through which three, almost completely separate sub-declensions, representing each gender, were created for each main declension.
