==Ethnonym== The etymology of the name "Severian" is uncertain. The name of the Severia region originated from the Slavic tribes. One theory proposes derivation from the Slavic word for "north" (sěver; men of the north), but the Severians never were the northernmost tribe of Slavs. Another theory proposes an Iranic derivation, from the name of the Sarmatian Seuer tribe (seu meaning "black"). Some scholars have argued that Jews called this tribe the Sawarta, based on the Kievan Letter (c. 930), written in Hebrew as SWRTH (read either as ''Sur'ata or Sever'ata), derived from Slavic sirota ("orphan"; in the letter, possibly meaning "convert"); or that the name "Severian" comes from the Magyar Savarti ("black"; possibly borrowed from Proto-Germanic swartaz). Based on the writings of the Bavarian Geographer, some scholars connect the ethnonym to the Zuierani, Zeriuani, or Sebbirozi (most probably the Sabirs).
