Kajkavian in the context of "Štokavian"

Serbo-Croatian, also known as Bosnian-Croatian-Montenegrin-Serbian (BCMS), is a South Slavic language and the primary language of Serbia, Croatia, Bosnia and Herzegovina, and Montenegro. It is a pluricentric language with four mutually intelligible standard varieties, namely Serbian, Croatian, Bosnian, and Montenegrin.

South Slavic languages historically formed a dialect continuum. The region's turbulent history, particularly due to the expansion of the Ottoman Empire, led to a complex dialectal and religious mosaic. Due to population migrations, Shtokavian became the most widespread supradialect in the western Balkans, encroaching westward into the area previously dominated by Chakavian and Kajkavian. Bosniaks, Croats, and Serbs differ in religion and were historically often part of different cultural spheres, although large portions of these populations lived side by side under foreign rule. During that period, the language was referred to by various names, such as "Slavic" in general, or "Serbian", "Croatian" or "Bosnian" in particular. In a classicizing manner, it was also referred to as "Illyrian".

Torlakian, or Torlak, is a group of transitional South Slavic dialects spoken across southeastern Serbia, southern and eastern Kosovo, northwestern and northeastern North Macedonia, and northwestern Bulgaria. Torlakian, together with Bulgarian and Macedonian, falls into the Balkan Slavic linguistic area, which is part of the broader Balkan sprachbund.

Torlakian is not standardized, and its subdialects vary significantly in some features. Yugoslav linguists traditionally classified it as an old Shtokavian dialect or as a fourth supradialect of Serbo-Croatian along with Shtokavian, Chakavian, and Kajkavian. Bulgarian scholars classify it as a Western Bulgarian dialect, in which case it is referred to as a Transitional Bulgarian dialect. According to UNESCO's list of endangered languages, Torlakian is a vulnerable distinct language.

Croatian is the standard variety of the Serbo-Croatian language mainly used by Croats. It is the national official language and literary standard of Croatia, one of the official languages of Bosnia and Herzegovina, Montenegro, the Serbian province of Vojvodina, the European Union and a recognized minority language elsewhere in Serbia and other neighbouring countries.

In the mid-18th century, the first attempts to provide a Croatian literary standard began on the basis of the Neo-Shtokavian dialect that served as a supraregional lingua franca – pushing back regional Chakavian, Kajkavian, and Shtokavian vernaculars. The decisive role was played by Croatian Vukovians, who cemented the usage of Ijekavian Neo-Shtokavian as the literary standard in the late 19th and the beginning of the 20th century, in addition to designing a phonological orthography. Croatian is written in Gaj's Latin alphabet.

Shtokavian or Štokavian (/ʃtɒˈkɑːviən, -ˈkæv-/; Serbo-Croatian Latin: štokavski / Serbo-Croatian Cyrillic: штокавски, pronounced [ʃtǒːkaʋskiː]) is the prestige supradialect of the pluricentric Serbo-Croatian language and the basis of its Bosnian, Croatian, Montenegrin and Serbian standards. It is a part of the South Slavic dialect continuum. Its name comes from the form for the interrogative pronoun for "what": što. This is in contrast to dialects that are exclusive to Croatian language: Kajkavian and Chakavian (kaj and ča also meaning "what").

Shtokavian is spoken in Bosnia and Herzegovina, the southern part of Austria's Burgenland, much of Croatia, Montenegro, Bosnia and Herzegovina and Serbia. The primary subdivisions of Shtokavian are based on three principles: one is different accents (whether the subdialect is Old-Shtokavian or Neo-Shtokavian), second is the way the old Slavic phoneme yat has changed (Ikavian, Ijekavian or Ekavian), and third is the presence of the Young Proto-Slavic isogloss (Schakavian or Shtakavian). Modern dialectology generally recognises seven Shtokavian subdialects.

Supradialect (from Latin supra, "above", and Ancient Greek διάλεκτος, "discourse") is a linguistic term designating a dialectological category between the levels of language and dialect. It is used in two distinctive contexts, describing structural or functional relations within a particular language. As a structural category, supradialects designate the first level of dialectological subdivision within a language, as for example in the pluricentric Serbo-Croatian language, which is divided into three basic supradialects (Shtokavian, Kajkavian and Chakavian), with each of them being further divided into several dialects. As a functional category, supradialect designates a predominant dialectal form within a particular language, referring to the most commonly used variant of that language, accepted in practice by the majority of its speakers as a basic tool of mutual interaction and communication. In that context, such supradialect also functions as an interdialect.

Gaj's Latin alphabet (Serbo-Croatian: Gajeva latinica / Гајева латиница, pronounced [ɡâːjeva latǐnit͡sa]), also known as abeceda (Serbo-Croatian Cyrillic: абецеда, pronounced [abet͡sěːda]) or gajica (Serbo-Croatian Cyrillic: гајица, pronounced [ɡǎjit͡sa]), is the form of the Latin script used for writing all four standard varieties of Serbo-Croatian: Bosnian, Croatian, Montenegrin, and Serbian. It contains 27 individual letters and 3 digraphs. Each letter (including digraphs) represents one Serbo-Croatian phoneme, yielding a highly phonemic orthography. It closely corresponds to the Serbian Cyrillic alphabet.

The alphabet was initially devised by Croatian linguist Ljudevit Gaj in 1835 during the Illyrian movement in ethnically Croatian parts of the Austrian Empire. It was largely based on Jan Hus's Czech alphabet and was meant to serve as a unified orthography for three Croat-populated kingdoms within the Austrian Empire at the time, namely Croatia, Dalmatia and Slavonia, and their three dialect groups, Kajkavian, Chakavian and Shtokavian, which historically utilized different spelling rules. The alphabet's final form was defined in the late 19th century.
