The Albanian language, known there in Albanian as arbërisht and in Greek as arvanitika , is still spoken to some extent in about three hundred twenty villages primarily in Boeotia (especially around Levadhia), southern Euboea, Attica, Corinth, and northern Andros.
The Albanian minority in Greece can be divided into two groups: those living in villages and settlements near the Albanian border and the largely assimilated Arvanites who populated much of central and southern Greece in the late Middle Ages.
Among the minority groups living with the Albanian majority are ethnic Greeks, Slavs, Aromunians (Vlachs), and Rom (Gypsies).
Albania is bordered to the north by the Yugoslav republic of Montenegro, which has an approximate 10 percent Albanian minority living in regions along the Albanian-Montenegrin border.
There is little evidence to prove or disprove this theory, since little is known about the Illyrian language.
Since ancient times, very substantial strata of Latin and of Slavic and Turkish have been added to Albanian, making the older strata more difficult to analyze.
It is estimated that about one-hundred thousand people from the traditional Italo-Albanian communities in southern Italy can still speak Albanian.
