The Romanian dialects (Romanian: subdialecte or graiuri) are the several regional varieties of the Romanian language (Daco-Romanian). The dialects are divided into two types, northern and southern, but further subdivisions are less clear, so the number of dialects varies between two and occasionally twenty. Most recent works seem to favor a number of three clear dialects, corresponding to the regions of Wallachia, Moldavia, and Banat (all of which actually extend into Transylvania), and an additional group of varieties covering the remainder of Transylvania, two of which are more clearly distinguished, in Crișana and Maramureș, that is, a total of five.
The main criteria used in their classification are the phonetic features. Of less importance are the morphological, syntactical, and lexical particularities, as they are too small to provide clear distinctions.
All Romanian dialects are mutually intelligible.
