text: Šumadija–Vojvodina Also known as Younger Ekavian, is one of the bases for the standard Serbian language. It is spoken by Serbs across most of Vojvodina (excluding easternmost parts around Vršac), northern part of western Serbia, around Kragujevac and Valjevo in Šumadija, in Mačva around Šabac and Bogatić, in Belgrade and in predominantly ethnically Serbian villages in eastern Croatia around the town of Vukovar. It is predominately Ekavian (Ikavian forms are of morphophonological origin). In some parts of Vojvodina the old declension is preserved. Most Vojvodina dialects and some dialects in Šumadija have an open e and o. However the vernaculars of western Serbia, and in past to them connected vernaculars of (old) Belgrade and southwestern Banat (Borča, Pančevo, Bavanište) are as close to the standard as a vernacular can be. The dialect presents a base for the Ekavian variant of the Serbian standard language.
