Rusakov, Alexander (2017). "Albanian". In Mate Kapović (ed.). The Indo-European Languages (2nd ed.). Routledge. ISBN 978-1-315-67855-9."The name with the root arb- is mentioned in old Albanian documents, but it went out of use in the main part of Albanian-speaking area and remains in use only in diaspora dialects (It.-Alb. arbëresh, Gr.-Alb. arvanitas). In other areas, it has been replaced by the term with the root shqip-."

ISBN 9783447062213."The ethnic name shqiptar has always been discussed together with the ethnic complex: (tosk) arbëresh, arbëror, arbër — (gheg) arbënesh, arbënu(e)r, arbën; i.e. [arbën/r(—)]. [...] Among the neighbouring peoples and elsewhere the denomination of the Albanians is based upon the root arb/alb, cp. Greek 'Αλβανός, 'Αρβανός "Albanian", 'Αρβανίτης "Arbëresh of Greece", Serbian Albanac, Arbanas, Bulg., Mac. албанец, Arom. arbinés (Papahagi 1963 135), Turk. arnaut, Ital. albanese, German Albaner etc. This basis is in use among the Arbëreshs of Italy and Greece as well."

OCLC 51036121."Today, the common name for Albanians, i.e. Albania, shqiptar, Shqiperia, is more recent. Albanians who settled in Greece in the Middle Ages and those who emigrated to Italy in the 15th century and later do not actually know about this name. The origin of the name Shqiptar is not clearly established. Until recently, the favorite interpretation was that it was derived from the Albanian shqipe "lord, nobility", thus "lord's sons". It is more likely, however, that the modern name given by the Albanians to themselves is derived from shqipon "to speak clearly" or from shqipton "to pronounce" (compared to the Slavic name nemci "dumb; those who do not speak intelligibly")."
