Yarilian

Yarilian is an East Slavic language spoken in Yarilia (Slavic country in the Caucasus region), but its grammar differs in some aspects a lot of Russian, Ukrainian and Belorusian.

Writing System
There're some ortography and pronounciation rules you should know :
 * 1) ь just occures if the palatalized consonant is followed by another consonant or if the palatalized consonant is the last letter of the word, e.g. ярiльскi (=Yarilian), ношчь (=night)
 * 2) й just occures after a vowel, e.g. Кiтай (=China)
 * 3) If a voiced sound comes at the end of a word, it becomes voiceless, e.g. град -- грат (=city), рад -- рат (=joy)
 * 4) ʃt is written by the digraph чт, e.g. что (=what), очтрафоваць (=to fine)
 * 5) If н is palatalized followed by a е at the end of the word, it has to be written by ннье (and not нѣ), e.g. очтрафованнье (=a/the fining), шуканнье (=a/the search)
 * 6) If ы is preceded by a palatalized vowel, it becomes i, e.g. день (=day) + ы = днi (=days)

Nouns
In Yarilian nouns are inflected coresponding to the cases (nominative, vocative, accusative, dative, genitive, instrumental, prepositional) and number (singular or plural). Yarilian nouns can be masculine, feminine or neuter. The ground form of a noun will always be the nominative singular.

First Declension 

Masculine : consonant mostly 
 * 1) Animate nouns (=persons or animals) get the genitive ending in the accusative case, e.g. муж (=man) -- мужа (accusative singular) -- мужов (accusative plural)
 * 2) Words ending in ў change into ль at the end if a case ending is added, e.g. пiсатеў (=writer) -- пiсателя (accusative/genitive singular) -- пiсателi (nominative/vocative/accusative plural)
 * 3) Words ending in й change into their palatalized vowel if a case ending is added, e.g. ґерой (=hero) -- ґероя (accusative/genitive singular) -- ґероi (nominative/vocative/accusative plural)
