Notable settlements include Železniki, Zgornja Sorica, Zali Log, Studeno, Dražgoše, Selca, Dolenja Vas, and Praprotno.

[3] The dialect still retains length distinctions, except for *ī and *ū, which became significantly shorter than other long vowels, and short *-ì and *-ù turned into schwa (ə).

It evolved from the southern proto-dialect, which was characterized by early lengthening of non-final vowels, which are now represented by the same sound.

[9] There is extensive syncope and a many short vowels were reduced, to an even greater extent than in the Upper Carniolan dialect.

[7] The cluster *šč, at least in the Selca dialect, has simplified into š, and palatal *ĺ and *ń depalatalized and merged with *l and *n, respectively.

[11] In Sorica in the westernmost part of the dialect, alveolar *s, *z, and *c merged with post-alveolar *š, *ž, and *č, respectively.
