Sawicka, Irena. "A Crossroad Between West, East and Orient–The Case of Albanian Culture." Colloquia Humanistica. No. 2. Instytut Slawistyki Polskiej Akademii Nauk, 2013.

The Rumanian grammar is almost identical to that of Albanian, but it may be as well the effect of later convergence within the Balkan Sprachbund.."
