In previous dialectological articles Kajkavian dialect which is spoken in Gorski kotar has been divided into two parts: western and eastern. In most cases the eastern subdialect has been compared with the speeches in Ozalj area, especially in context of accentuation and vocalism. In doctoral thesis Phonology and morphology of the Kajkavian Speeches of Eastern Gorski kotar it has been researched 19 local speeches which in previous dialectological articles have been specified like parts of eastern subdialect of goranski dialect: Lukovdol, Gorenci, Dolenci, Podvučnik, Rtić, Draga Lukovdolska, Nadvučnik, Vučnik, Severin na Kupi, Močile, Klanac, Damalj, Plešivica, Rim, Liplje, Mali Jadrč, Veliki Jadrč, Osojnik i Smišljak. Preliminary research of the most important phonological and morphological characteristcs showed that all these local speeches can be divided into three groups. Local speeches of Osojnik, Smišljak and Lukovdol have been then choosed like representative. Phonological descriptions of these three vernaculars showed that local speech of Osojnik in accentuation shows the biggest difference from the remaining analyzed speeches. In this speech are deduced many accent retractions: at the last syllable there isn't any accent, neither short neither long. Short accent also usually can't stay at medial syllable. In local speeches of Smišljak and Lukovdol long accent can stay at the last syllable, also the short accent at medial syllable. The accent inventory of prosodems is the same in all the vernaculars − relevant is the position of the stress and its quantity. The unstressed lengthenings in the entire subdialect have disappeared. Metatonic circumflex in all speeches in some examples reflected like long accent, and in some examples metathony didn't conducted. The short reflex of metatonic circumflex in local speech of Osojnik also shift at first syllable. In local speeches of Smišljak and Lukovdol there are some examples of progresive shift of primary circumflex. In vocalism local speeches of Osojnik and Smišljak are the same. Local speech of Lukovdol from them is different in unstressed vocalism. Also, in this speech there is in use pronoun kˈe, and in other two speeches there is in use pronoun kˈaj. In morphology local speeches of Smišljak and Osojnik are also very similar (almost the same). Local speech of Lukovdol is different in several segments: there is saved origin 300 distinction between two old main declensions, palatal and non-palatal. Also, in invetory of gramatical morphems in this speech there is registered new morphem -ima. Phonological and morphological analysis of these speeches showed that area of the east Gorski kotar in dialectological sense is intertwined by many isoglosses. Result of this is area partition at three groups of speeches: southeastern (speeches around Osojnik), central (speeches around Smišljak) and northwestern (speeches around Lukovdol). Besides, in this thesis there is noticed that there is need for revision of some traditional comprehensions about some characteristcs which usually were joined only to one group of dialect, because in all analyzed local speeches of the eastern Gorski kotar (especially in local speech of Osojnik) were confirmed many characteristics which today exist in local speeches of all three groups of dialects.
