Albanian (endonym: shqip [ʃcip] , gjuha shqipe [ˈɟuha ˈʃcipɛ] , or arbërisht [aɾbəˈɾiʃt]) is an Indo-European language and the only surviving representative of the Albanoid branch, which belongs to the Paleo-Balkan group. It is the native language of the Albanian people. Standard Albanian is the official language of Albania and Kosovo, and a co-official language in North Macedonia and Montenegro, where it is the primary language of significant Albanian minority communities. Albanian is recognized as a minority language in Italy, Croatia, Romania, and Serbia. It is also spoken by long-established communities in Greece, and by the Albanian diaspora, which is generally concentrated in the Americas, Europe, and Oceania. Albanian is estimated to have as many as 7.5 million native speakers.
Albanian and other Paleo-Balkan languages had their formative core in the Balkans after the Indo-European migrations in the region. Albanian in antiquity is often thought to have been an Illyrian language for obvious geographic and historical reasons, or otherwise an unmentioned Balkan Indo-European language that was closely related to Illyrian and Messapic. The Indo-European subfamily that gave rise to Albanian is called Albanoid in reference to a specific ethnolinguistically pertinent and historically compact language group. Whether descendants or sisters of what was called 'Illyrian' by classical sources, Albanian and Messapic, on the basis of shared features and innovations, are grouped together in a common branch in the current phylogenetic classification of the Indo-European language family.
