In this article, a detailed phonological description of the Chakavian idioms of the Zadar mainland is given. The description includes some principal morphological features as well. The article is based on the examples obtained from the native speakers of the idioms during the field research of the author. In the first two chapters, the historicalgeographic context and the methodology are explained. After this, some general features of the Chakavian idioms of the Zadar mainland are given. The phonological description includes vocalism, consonantism and accentology. Each feature is explained and exemplified for each Chakavian idiom, comparing them to the adjacent Shtokavian idioms. The morphological description includes examples of noun and verb forms. In the conclusion, two main statements are given. Despite the great influence that Shtokavian idioms of the adjacent villages have made to the phonology and the morphology of the Chakavian idioms in question, their Chakavian origin is confirmed by some characteristic archaisms (accentology in the first place). At the end of the article, the examples of some idioms in question are given, which are obtained from the transcription of the spontaneous speech of the native speakers.
