The standard Slovak language and the standard Macedonian language originated in accordance with divergent tendencies of the development of standard Slavic languages. Despite the historical, political, cultural and social differences in developments of the Slovak nation and the Macedonian nation (1) both standard languages are based on the central dialects, i. e., the central Slovak interdialect in Slovakia and the central Macedonian interdialect in Macedonia; (2) both standard languages follow the rule of including the lexis of all national dialects, i. e., eastern and western dialects of Slovak and Macedonian language; and (3) the orthography of the both standard languages is based on a phonetical (morphonological) principle. We suppose that this coherence was a result of the similar principles of the codification processes of both standard languages, and that the first codifier of the standard Macedonian language, Krste P. Misirkov, was familiar with the linguistic works of the Slovak codifier Ludovit Stur.
