Like the Šavrin Hills subdialect, the Rižana subdialect is based on characteristics of the Lower Carniolan and Littoral dialect groups. Accented vowels do not have length contrast. Secondary palatalization of the velars k g h has arisen before front vowels. Verbal conjugation lacks the dual. The two subdialects share many lexical features, with many loanwords from Romance languages.
