Schei; Şcheii; Shkei; Șcheii; Shqa; Şchiau; Şchei
Șchei (, shkei) was an old Romanian exonym referring to the Bulgarians, especially in Transylvania and northern Wallachia. As a name, it has been preserved in the names of towns colonized in the 14th century by Bulgarians, in toponyms (Dealu Schiaului near Rășinari), hydronyms (Schiau River, tributary to the Argeş River), surnames (Schiau, Șchiau).Mușlea, Șcheii de la Cergău… The word is thought to derive from Latin sclavis, a popular designation for the South Slavs (Bulgarians and Serbs in particular) that is still used in Albanian (in the form shkja and various dialectal variants).
