Although not a regulated dialect (its speakers considering it a dialect of Slovene rather than a different language), and without any official status of its own within Italy, speakers of Resian maintain a Roman based script separate from that used for standard Slovene. The alphabet contains the letter /W/, which is a rare grapheme among Slavic languages; the exceptions being Polish and Lusatian.
Written Resian can mostly be understood by Slovenians, but spoken Resian is much harder to understand. Resian, forming a part of the South Slavic dialect continuum, shares numerous features with the Slovenian dialects spoken across the adjacent border, and communication between the communities is intelligible. However, Resian and standard Slovenian are mutually unintelligible due to archaisms not preserved in modern Slovenian, and a significant Italian influence on Resian vocabulary and pronunciation.
