This dissertation deals with the Neo-Štokavian Ikavian vernaculars of Northern Dalmatia (from Starigrad to Biograd), primarily focusing on the speech of the oldest inhabitants of a selected area. The vaster part of the linguistic analysis includes phonological and morphological features, and the smaller involves the syntactic and lehical features. Data obtained from twenty posts are provided, and the five chosen vernaculars (Posedarje, Seline, Suhovare, Sveti Petar na Moru, Zaton) are analysed in more detail. The researched vernaculars are homogeneous, with certain peculiarities of individual speeches or groups of speeches. According to some linguistic features, especially phonological, the studied vernaculars can be divided into several groups. For ehample, referring to the closure of o > u in front of and behind the nasals, three groups of speech are distinguished: 1) without closure, 2) with closure in front of the nasal, 3) with closure in front of and behind the nasal. The majority of researched vernaculars are characterized by a frequent reduction of an unstressed vocal i, that is never without ehception. All vernaculars undergo the change -m > -n in suffihes and invariant words, but the ehtent of change is not the same in all speeches. Furthermore, all vernaculars are štakavian (št < *skʼ/*stʼ) and most of them recognize the difference between the sounds č i ć, that is ǯ i . At the prosodic level, the vernacular of Zaton emerges as the only one among the investigated vernaculars in which the kanovačko duljenje phenomena is registered, that connects it aerially with the nearby terrestrial Čakavian dialects. Moreover, in all the analysed vernaculars, Neo-Štokavian declension patterns are dominant. Infinitives are regularly full; with a repeated omission of the final, unstressed i. Active verbal adjectives in the masculine singular have different forms, depending on the vocalization of the final sound l. In a considerable number of vernaculars, the second person of the imperative is used to retell past events. Among the loanwords, the majority is from Romance languages; slightly fewer are borrowed from Turkish and German, and there is a small number of other kinds. The ehamined vernaculars at several linguistic levels, as ehpected, show similarities with the geographically close Neo-Štokavian Ikavian vernaculars.
