Shtokavian or Štokavian (/ʃtɒˈkɑːviən, -ˈkæv-/; Serbo-Croatian: štokavski / штокавски, pronounced [ʃtǒːkaʋskiː])[2] is the prestige dialect of the pluricentric Serbo-Croatian language and the basis of its Serbian, Croatian, Bosnian and Montenegrin standards.[3] It is a part of the South Slavic dialect continuum.[4][5] Its name comes from the form for the interrogatory pronoun for "what" in Western Shtokavian, što (it is šta in Eastern Shtokavian). This is in contrast to Kajkavian and Chakavian (kaj and ča also meaning "what").

Shtokavian is spoken in Serbia, Montenegro, Bosnia and Herzegovina, much of Croatia, as well as the southern part of Austria’s Burgenland. The primary subdivisions of Shtokavian are based on two principles: one is whether the subdialect is Old-Shtokavian or Neo-Shtokavian, and different accents according to the way the old Slavic phoneme jat has changed. Modern dialectology generally recognises seven Shtokavian subdialects.

Also called Eastern Herzegovininan or Neo-Ijeka

Also called Eastern Herzegovininan or Neo-Ijekavian. It encompasses by far the largest area and the number of speakers of all Shtokavian dialects. It is the dialectal basis of the standard literary Croatian, Bosnian, Serbian, and Montenegrin languages.
