Mostly spoken dialect on the Istrian peninsula is Chakavian dialect. According to generally accepted classification by Dalibor Brozović in Istria there is widespread five of the six Croatian dialects, most of which takes south-west Istrian or Shtokavian-Chakavian dialect. The Shtokavian-Chakavian dialect is not the original dialect, but migration because it was "brought" by immigrants from Dalmatia who were escaping from the Turks in the 16th century. The most important characteristics of Chakavian dialect are: pronoun ČA, reflex yat, accentuation (the most important phonological criterion), a reflection of the front and back nasals, a reflection of phonemes , morphonological alternations and other language features. The greatest variety in the Istrian speeches is recorded in the pronoun ČA which has a three-fold reflection: ČA, KAJ and CA and accentuation, because some of that speeches kept three - accent old system, in others unaccented lenghts have been cutted, while others speeches were completely lost the acute (two-accent system) or the acute was created by transmission of short-falling accent from the last syllable (new three-accent system), and even in one village near Labin is recorded one-accent system. For all these reasons it is difficult to determine which accentual system prevails in Istria. The biggest particularities compared to other Istrian speeches and subsystems of the Croatian language were recorded in Buzet or gornjomiranskom dialect. Numerous of contemporary authors, who nurture chakavian Istrian expression in their literary works also prove that a „Chakavian word“ is still "alive". In this way, they contribute to the conservation of chakavian Istrian dialects, as well as certain local dialects.
