Albanian language is the key of Proto-Indo-European languages. The aim of this paper is to research for the role and the operation of Albanian language in Balkans. The Albanian language is spoken by seven million people in the south-western of Balkans. Albanian is a language of the extensive Indo-European family and is thus related to a certain degree to almost all other languages of Europe. Albanian is officially spoken in the Republic of Albania and Kosova. Traditional Albanian settlements can be encountered sporadically elsewhere in Arbansi of Zadar (in Croatian); in some cities of Serbia; Macedonia; Montenegro and in the Bulgarian-Greek-Turkish border region. A few Albanian speakers are also to be found in the Ukraine (village in the regions Melitopol’ and Odessa) and notably in villages in Bulgarian (in Mandrica). As a geographical and cultural entity, and as a nation, Albania has often been enigmatic. The first document in Albanian language is: Paulus Angelus, 1462 “I baptize thee in the name of the Father and the Son and the Holy Spirit".
