Franz Altheim derived the title from Iranian etymon *fsu-pāna- that evolved to uβān in Parthian, upān and ubān in Persian; all these words meaning "shepherd".[17][18] Gerhard Doerfer suggested possible Iranian origin for Mahmud al-Kashgari's čupan linking it with New Persian čōpan, a variant form of ubān, with usual change of - to č-.[17] Omeljan Pritsak in Iranian *fsu-pāna saw "shepherd of (human) cattle" in Avar service, using the Slavic masses as cannon fodder.[17] Some scholars derived it from alleged Old Iranian aurpan/aszurpan, meaning "great lord, noblemen".[19][20] It is considered that the title origin can be traced to the Slavic and Iranian cultural interrelation in the Eastern and Southeastern Europe in the first centuries AD.[19][20]
