The Wallachian dialect (subdialectul / graiul muntean / muntenesc) is one of the several dialects of the Romanian language (Daco-Romanian). Its geographic distribution covers approximately the historical region of Wallachia, occupying the southern part of Romania, roughly between the Danube and the Southern Carpathians. Standard Romanian, in particular its phonology, is largely based on Wallachian. As with all other Romanian dialects, Wallachian is distinguished primarily by its phonetic characteristics and only marginally by morphological, syntactical, and lexical features.
