The Zeta dialect features additional sounds: a voiceless alveolo-palatal fricative (), voiced alveolo-palatal fricative *(, (occurring in other jekavian dialects as well) and a voiced alveolar affricate (, shared with other old-štokavian dialects). Both sub-dialects are characterised by highly specific accents (shared with other old-štokavian dialects) and several "hyper-ijekavisms" (i.e. "nijesam", where the rest of shtokavian area uses "nisam") and "hyper-iotations" ("đevojka" for "djevojka", "đeca" for "djeca" etc.) (these features, especially the hyper-iotation, are more prominent in the Zeta sub-dialect), that are common in all Montenegrin vernaculars.
