西スラヴ語群
The ultimate output of the third palatalization is thus the same as that of the preceding second palatalization. The difference of the palatalization of *x is dependent upon chronology and the Slavic dialect in question: In East and South Slavic it is /s/, and in West Slavic languages it is /š/. Slovak tends to match South Slavic in such instances, e.g. "Čech" "Czech", plural "Česi" "Czechs".
