text: The Ikavian pronunciation is the only one that is not part of any standard variety of Serbo-Croatian today, though it was a variant used for a significant literary output between the 15th and 18th centuries. This has led to a reduction in its use and an increase in the use of Ijekavian in traditionally Ikavian areas since the standardization. For example, most people in formerly fully Ikavian Split, Croatia today use both Ikavian and Ijekavian words in everyday speech, without a clearly predictable pattern (usually more emotionally charged or intimate words are Ikavian and more academic, political, generally standardised words Ijekavian, but it is not a straight out rule).
  The IETF language tags have assigned the variants  and  to Ekavian and Ijekavian pronunciations, respectively.
  Ethnic affiliation of native speakers of Shtokavian dialect
  During the first half of the 19th century, protagonists of nascent Slavic philology were, as far as South Slavic dialects were concerned, embroiled in frequently bitter polemic about "ethnic affiliation" of native speakers of various dialects. This, from contemporary point of view, rather bizarre obsession was motivated primarily by political and national interests that prompted philologists-turned-ideologues to express their views on the subject. The most prominent contenders in the squabble, with conflicting agenda, were the Czech philologist Josef Dobrovský, the Slovak Pavel Šafárik, the Slovenes Jernej Kopitar and Franz Miklosich, the Serb Vuk Karadžić, the Croat of Slovak origin Bogoslav Šulek, and the Croatians Vatroslav Jagić and Ante Starčević.
  The dispute was primarily concerned with who can, philologically, be labelled as "Slovene", "Croat" and "Serb" with the aim of expanding one's national territory and influence. Born in the climate of romanticism and national awakening, these polemical battles led to increased tensions between the aforementioned nations, especially because the Shtokavian dialect cannot be split along ethnic lines in an unequivocal manner.
