Shtokavian dialect
The Eastern Herzegovinian dialect (, Serbo-Croatian: "istočnohercegovački"/источнохерцеговачки or "istočnohercegovačko-krajiški"/источнохерцеговачко-крајишки) is the most widespread subdialect of the Shtokavian dialect of Serbo-Croatian, 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 (the latter only partially codified).
