« Lombard (Lumbard, ISO 639-9 lmo) is a cluster of essentially homogeneous varieties (Tamburelli 2014: 9) belonging to the Gallo-Italic group. It is spoken in the Italian region of Lombardy, in the Novara province of Piedmont, and in Switzerland. Mutual intelligibility between speakers of Lombard and monolingual Italian speakers has been reported as very low (Tamburelli 2014). Although some Lombard varieties, Milanese in particular, enjoy a rather long and prestigious literary tradition, Lombard is now mostly used in informal domains. According to Ethnologue, Piedmontese and Lombard are spoken by between 1,600,000 and 2,000,000 speakers and around 3,500,000 speakers respectively. These are very high figures for languages that have never been recognised officially nor systematically taught in school »
