in Croatia (Arbanasi and Istrian), Kosovo, Montenegro and Northwestern North Macedonia are Gheg dialects, while those dialects spoken in Greece (Arvanites and Çam), Southwestern North Macedonia and Italy (Arbëreshë) are Tosk dialects. The Arbëreshë and Arvanitika languages represent varieties of the Albanian language spoken by the Arbëreshës and Arvanites in Southern Italy and Southern Greece respectively. They retain elements of medieval Albanian vocabulary and pronunciation that are no longer used in modern Albanian language however both varieties are classified as endangered languages in the UNESCO Red Book of Endangered Languages. Most of the Albanians in Albania and the Former Yugoslavia are polyglot and have the ability to understand, speak, read, or write a foreign language. As defined by the Institute of Statistics of Albania, 39.9% of the 25 to 64 years old Albanians in Albania are able to use at least one foreign language including English (40%), Italian (27.8%) and Greek (22.9%). The origin of the Albanian language remains a contentious subject that has given rise to numerous hypotheses. The hypothesis of Albanian being one of the descendant of the Illyrian languages (Messapic language) is based on geography where the languages were spoken however not enough archaeological evidence is left behind to come therefore to a definite conclusion. Another hypothesis associates the Albanian language with the Thracian language. This theory takes exception to the territory, since the language was spoken in an area distinct from Albania, and no significant population movements have been recorded in the period when the shift from one language to the other is supposed to have occurred. History Late Antiquity The Komani-Kruja culture is an archaeological culture attested from late antiquity to the Middle Ages in central and northern Albania, southern Montenegro and similar sites in the western parts of North Macedonia. It consists of settlements usually built below hillforts along the Lezhë (Praevalitana)-Dardania and Via Egnatia road networks which connected the Adriatic coastline with the central Balkan Roman provinces. Its type site is Komani and its fort on the nearby Dalmace hill in the Drin river valley. Kruja and Lezha represent significant sites of the culture. The population of Komani-Kruja represents a local, western Balkan people which was linked to the Roman Justinianic military system of forts. The development of Komani-Kruja is significant for the study of the transition between the classical antiquity population of Albania to the medieval Albanians who were attested in historical
