Kusian language

Modern standard Kusian descends from and is characterized by a number of sound changes and morphological developments, many of which are shared with other North Slavic languages. These include:


 * : The Common Slavic combinations, *CoRC and *CeRC, where R is either *r, *p or *l, become in Kusian:
 * 1) CorC gives CoroC (Common Slavic *borda gives old-Kusian boroda, which is modern Kusian barauda)
 * 2) ColC gives ColoC (Common Slavic *bolto gives old-Kusian bolotus, which is modern Kusian balautús)
 * 3) CerC gives CereC (Common Slavic *berza gives old-Kusian bwereža, which is modern Kusian ''bwéreža)
 * 4) CelC gives ColoC (Common Slavic *melko gives old-Kusian molokus, which is modern Kusian malaukús)
 * 5) The Common Slavic nasal vowel *ę and other nasal sounds retained in modern day Kusian language, in comparison to other Slavic languages
 * 6) word-initially, where it became : Common Slavic *(j)ěsti became modern Kusian ojśći /ˈoj'sʲt͡sʲi/
 * 7) after the postalveolar sibilants where it became : Common Slavic *ležěti became Kusian ĺegwajaći /lʲeˈg͡wɑjɑt͡sʲi/)
 * 8) Common Slavic *i and *y are both reflected in Kusian as /ɪ/, unless placed before palatalised consonant when they become /i/

Written language
Sequences of /dž, dź, dz, rź, vĺ, wĺ, gw, kw/ merge to create sounds /d͡ʒ, d͡zʲ, d͡z, r͡zʲ, v͡lʲ, w͡lʲ, g͡w, k͡w /. Number of vowels change their properties when being written after palatalised consonants: * I changes from [ɪ] to [i] * U changes from [u] to [ɯ] * O changes from [o] to [ø̞]
