Kessian
Льисьма Кеңам

Kessian is supposed to be an Indo European language spoken in northeastern Siberia. I started working on it back in the winter of '25. It's still pretty unfinished; it lacks a lot of basic vocabulary and, as of now, a fleshed out system of numerals. So described here is just an outline of the sounds and nominal morphology.

[1] All dentialveolar consonants except for /z̞~z/ become their palatal equivalents before a front vowel.
[2] /w/ and /j/ become /iː/ and /uː/ between a consonant and a word boundary.

[1] /iː/ and /uː/ become /j/ and /w/ when before a vowel.

All nouns fall into one of two genders: animate and neuter. There are three numbers: singular, dual and plural. And there are five cases: nominative, genitive, ablative, instrumental and translative. All nominals fall into one of four eight seven classes. Adjectives agree in gender, number and case with the nouns they modify.

Class-Ia nominals have the ending -0 or -ом (the former is animate, the latter in neuter) in their nominative-singular form. They can be either animate or neuter.
Class-Ib nominals are the same as Class-Ia except they have the ending -ё in the nominative-singular.
Class-IIa nominals have -а in the nominative-singular. They can only be animate.
Class-IIb nominals are the same as Class-IIa except they have the ending -я in the nominative-singular.
Class-IIIa nominals have -эр in the nominative singular. They can only be animate.
Class-IIIb nominals have -οр in the nominative singular. They can only be animate.
Class-IV nominals have -ам in the nominative-singular. They can only be neuter. Class-IV derives from the PIE suffix -mṇ.
