areas of public life. In 2004 it became one of the official languages of the European Union upon Slovenia's admission. Joža Mahnič, a literary historian and president of the publishing house Slovenska matica, said in February 2008 that Slovene is a language rich enough to express everything, including the most sophisticated and specialised texts. In February 2010, Janez Dular, a prominent Slovene linguist, commented that, although Slovene is not an endangered language, its scope has been shrinking, especially in science and higher education. Geographic distribution The language is spoken by about 2.5 million people, mainly in Slovenia, but also by Slovene national minorities in Friuli-Venezia Giulia, Italy (around 90,000 in Venetian Slovenia, Resia Valley, Canale Valley, Province of Trieste and in those municipalities of the Province of Gorizia bordering with Slovenia), in southern Carinthia, some parts of Styria in Austria (25,000) and in west part Croatian Istria bordering with Slovenia. It is also spoken in Rijeka and Zagreb (11,800-13,100), in southwestern Hungary (3-5,000), in Serbia (5,000), and by the Slovene diaspora throughout Europe and the rest of the world (around 300,000), particularly in the United States (most notably Ohio, home to an estimated 3,400 speakers), Canada, Argentina, Australia and South Africa. Dialects Slovene is sometimes characterized as the most diverse Slavic language in terms of dialects, with different degrees of mutual intelligibility. Accounts of the number of dialects range from as few as seven dialects, often considered dialect groups or dialect bases that are further subdivided into as many as 50 dialects. Other sources characterize the number of dialects as nine or eight. The Slovene proverb "Every village has its own voice" (Vsaka vas ima svoj glas) depicts the differences in dialects. Although pronunciation differs greatly from area to area, those differences do not pose major obstacles to understanding. The standard language is mainly used in public presentations or on formal occasions. The Prekmurje dialect used to have a written norm of its own at one point. The Resian dialects have an independent written norm that is used by their regional state institutions. Speakers of those two dialects have considerable difficulties with being understood by speakers of other varieties of Slovene, needing code-switching to Standard Slovene. Other dialects are mutually intelligible when speakers avoid the excessive usage of regionalisms. Regionalisms are mostly limited to culinary and agricultural expressions, although there are many exceptions. Some loanwords have become so deeply rooted
