Matranga & Milano 2019, p. 228: "1. Arbëresh is the name used to indicate the linguistic varieties spoken by descendants of groups of Albanian immigrants in southern Italy from the middle of the fifteenth century. The Albanian varieties are divided into Gheghe varieties, spoken (by the Shqiptarë) in the northern part of the albanophone territory, in Kosovo and in Macedonia, and Tosche varieties, spoken in the southern part of Albania (by the Shqiptarë), in some areas of Greece (by the Arvaniti) and in Southern Italy (by the Arbëreshë)."

Liakopoulos 2022, p. 307:The Albanians, also known as Arvanites in the Greek lands, were first mentioned in the Peloponnese in the second half of the fourteenth century. By 1391 there had been an influx of Albanians that could be hired as mercenaries. The Venetians were in need of colonists and soldiers in their depopulated areas and hence offered plots of arable land, pastures and tax exemptions to the wandering Albanians in southern Greece (Thiriet 1959: 366; Chrysostomides 1995: 206, 291, 337, 339; Topping 1980: 261–71; Ducellier 1968: 47–64). A well-attested-to, more populous Albanian settlement took place during the rule of Theodore I Palaeologus (1384–1407), when ten thousand Albanians appeared before the Isthmus and asked Theodore for permission to settle in the Peloponnese (1394-95). A second wave of immigrants from southern Albania and western mainland Greece descended on the Peloponnese, perhaps in 1417-17. Their establishment was significant for the invigoration of the Albanian demographiy in the peninsula that led to the Albanian rebellion in 1453 Liakopoulos, Georgios C. (2022).

Jenny Frost, The Arbëreshë: Italy’s Albanian Diaspora, The Cambridge Language Collective: "Arbëresh (or Arbërisht) is the language spoken by the Arbëreshë community in Italy, descending from a medieval Tosk variety and containing influences from Italian. However, the language is now considered endangered; there are estimated to be fewer than 80,000 remaining native speakers worldwide. This can be put down to multiple factors: while some schools and universities in Rome and Southern Italy do teach the Albanian language, the version taught is standard Albanian rather than Arbëresh. Additionally, young people are often reluctant to use Arbëresh, preferring to use Standard Italian or Italo-Romance dialects, and because forms of Arbëresh can differ between communities, standard Albanian can sometimes be used as a lingua franca."

Matranga 2018, p. 14: È ormai ampiamente condivisa l’opinione che le varietà italo-albanesi appartengano al ceppo dialettale tosco, ossia a quelle varietà diffuse nell’Albania meridionale e nella Grecia (quest’ultime note col nome di arvanit), mentre in quella settentrionale e nel Kosovo sono presenti parlate del ceppo ghego. p. 73: "Più opportunamente, esse proverrebbero da diverse contrade balcaniche dell’Impero bizantino, in parte già sotto dominio turco-ottomano, corrispondenti a regioni della attuale Albania e della Grecia, sia insulare che peninsulare."
