Shtokavian in the context of "Serbo-Croatian language"

Serbian is the standard variety of the Serbo-Croatian language mainly used by Serbs. It is the official and national language of Serbia, one of the three official languages of Bosnia and Herzegovina, and co-official in Montenegro and Kosovo. It is a recognized minority language in Croatia, North Macedonia, Romania, Hungary, Slovakia, and the Czech Republic.

Serbian is based on the most widespread dialect of Serbo-Croatian, Shtokavian (more specifically on the dialects of Šumadija-Vojvodina and Eastern Herzegovina), which is also the basis of standard Croatian, Bosnian, and Montenegrin varieties. Reflecting this shared basis, the Declaration on the Common Language of Croats, Bosniaks, Serbs, and Montenegrins was issued in 2017. The other dialect spoken by Serbs is Torlakian in southeastern Serbia, which is transitional to Macedonian and Bulgarian.

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.

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.

Šumadija–Vojvodina dialect (Serbo-Croatian: шумадијско-војвођански дијалект / šumadijsko-vojvođanski dijalekt) is a dialect of Shtokavian / Serbo-Croatian. It is a base for Ekavian Standard Serbian.

The Eastern Herzegovinian dialect (/ˌhɛərtsəɡəˈviːniən, ˌhɜːr-, -ɡoʊ-, -ˈvɪn-/, Serbo-Croatian: istočnohercegovački dijalekt / источнохерцеговачки дијалект) is the most widespread subdialect of the Shtokavian supradialect or language, both by territory and the number of speakers. It is the dialectal basis for all modern literary Serbo-Croatian standards: Bosnian, Croatian, Serbian, and Montenegrin (in this last only partially codified).
