Serbian (Serbian Cyrillic: српски, Latin: srpski, pronounced [sr̩̂pskiː]) is the standardized variety of the Serbo-Croatian language used chiefly by Serbs in Serbia, Montenegro, and Bosnia and Herzegovina. In addition, it is a recognized minority language in Croatia, Macedonia, Romania, Hungary, Slovakia, the Czech Republic, Albania and Greece. Classification Serbian is a standardized form of Serbo-Croatian, a Slavic language(Indo-European), of the South Slavic subgroup. Other standardized forms of Serbo-Croatian are Bosnian, Croatian, and Montenegrin. It has lower intelligibility with the East South Slavic languages Bulgarian and Macedonian, than with Slovene (although Slovene is part of the West Slavic subgroup, it is hindered by differences in vocabulary, grammar and pronunciation to the Serbo-Croatian standard forms, and is closer to the Serbo-Croatian Kajkavian and Chakavian dialects. Historical dictionaries Vuk Karadžić's Srpski rječnik, first published in 1818, is the earliest dictionary of modern literary Serbian. The Rječnik hrvatskoga ili srpskoga jezika (I–XXIII), published by the Yugoslav Academy of Sciences and Arts from 1880 to 1976, is the only general historical dictionary of Serbo-Croatian. Its first editor was Đuro Daničić, followed by Pero Budmani and the famous Vukovian Tomislav Maretić. The sources of this dictionary are, especially in the first volumes, mainly Štokavian. There are older, pre-standard dictionaries, such as the 1791 German–Serbian dictionary. Education Education in Serbia is divided into preschool (predškolsko), primary school(osnovna škola), secondary school (srednja škola) and higher education(visoko obrazovanje) levels. It is regulated by the Ministry of Education and Science of Republic of Serbia.
