Jeong criticize the Yeniseian proposal by Pulleyblank and note that the more convincing Yeniseian words may be shared cultural vocabulary that was non-native to both the Xiongnu and the Yeniseians. Indo-European All three words described as "Hunnic" by ancient sources appear to be Indo-European. A number of scholars suggest that a Germanic language, possibly Gothic, may have coexisted with another Hunnic language as the lingua franca of the Hunnic Empire. Maenchen-Helfen suggests that the words medos and kamos could possibly be of Germanic origin. He argues that Attila, Bleda, Laudaricus, Onegesius, Ragnaris, and Ruga are Germanic, while Heather also includes the names Scottas and Berichus. Kim questions the Germanic etymologies of Ruga, Attila, and Bleda, arguing that there are "more probable Turkic etymologies." Elsewhere, he argues that the Germanicization of Hunnic names may have been a conscious policy of the Hunnic elite in the Western part of the Empire. Maenchen-Helfen also classified some names as having roots in Iranian. Christopher Atwood has argued, as one explanation for his proposed etymology of the name Hun that, "their state or confederation must be seen as the result of Sogdian/Baktrian [Iranian-speaking] leadership and organization". Subjects of the Huns included Iranian-speaking Alans and Sarmatians, Maenchen-Helfen argues that the Iranian names were likely borrowed from the Persians and finds none prior to the 5th century; he takes this to mean that the Alans had little influence inside of Attila's empire. Kim, however, argues for a considerable presence of Iranian-speakers among the Huns. The word strava has been argued to be of Slavic origin and to show a presence of Slavic speakers among the Huns. Peter Heather, however, argues that this word "is certainly a very slender peg upon which to hang the claim that otherwise undocumented Slavs played a major role in Attila's empire". In the 19th century, some Russian scholars argued that the Huns as a whole had spoken a Slavic language. Uralic In the 19th century, some scholars, such as German Sinologist Julius Heinrich Klaproth, argued that the Huns had spoken a Finno-Ugric language and connected them with the ancient Hungarians. Possible script It is possible that a written form of Hunnic existed and may yet be identified from artifacts. Priscus recorded that Hunnic secretaries read out names of fugitives from a written list. Franz Altheim considered it was not Greek or Latin, but a script like the Oguric Turkic of the Bulgars.
