This handbook provides a systematic, up-to-date overview of the Friulian language, both from a synchronic and from a diachronic perspective. Among other things, it presents in-depth discussions of current problems related to regional multilingualism (Friulian beside Italian as dachsprache, Venetian, German, and Slovenian) as well as of linguistic policies and important sociolinguistic aspects (e.g., the standardization of spelling and vocabulary, or the use of Friulian in the (new) media).
