Marin Temperica
The Catholic Reformists believed that it was necessary to determine what would be the most understandable language version on the territory populated by South Slavs. Temperica emphasized the importance of the Slavic literary language understandable all over the Balkans. In the report, he uses the Latin term "lingua sclavona" (lit. "Slavonian language") or "scalavona" (lit. Slavic language) for the vernacular of Bosnia, Serbia and Herzegovina, while naming Church Slavonic as the literary language. Temperica insisted on Shtokavian as most widespread on the Balkans. He reported that the same language was spoken on the territory between Dubrovnik and Bulgaria, in Bosnia, Serbia and Herzegovina, being most appropriate basis for common South Slavic literary language.
