Albanian (endonym: Shqip; Glotto: alba1268) is an Indo-European language which has been suggested to form an independent branch of the Indo-European family since the middle of the nineteenth century (Bopp 1855, Pedersen 1897, Çabej 1976). Though the origin of the language has been debated, the prevailing opinion in the literature is that it is a descendant of Illyrian (Hetzer 1995). Albanian is currently spoken by around 6–7 million people (Rusakov 2017: 552; Curtis 2018: 1800), the majority of whom live in Albania and Kosovo, with others in Italy, Greece, North Macedonia and Montenegro. Figure 1 shows a map of the main Albanian-speaking areas of Europe, with major linguistic subdivisions according to Gjinari (1988) and Elsie & Gross (2009) marked by different colours and shades.
