This is a cuneiform inscription composed in Akkadian, perhaps in the 8th century BCE, but no Median names are mentioned in it.
"[6] Words of Median origin include: A distinction from other ethnolinguistic groups such as the Persians is evident primarily in foreign sources, such as from mid-9th-century BCE Assyrian cuneiform sources[19] and from Herodotus' mid-5th-century BCE secondhand account of the Perso-Median conflict.
Median forms "are found only in personal or geographical names... and some are typically from religious vocabulary and so could in principle also be influenced by Avestan....
In the mid-5th century BCE, Herodotus (Histories 1.110[22]) noted that spaka is the Median word for a female dog.
[25] Consequently, these compositions have "certain linguistic affinities" with Parthian, but the surviving specimens (which are from the 9th to 18th centuries CE) are much influenced by Persian.
[26] The term Pahlav/Fahlav (see fahlaviyat) in traditional medieval Persian sources is also used to refer to regionalisms in Persian poetry from western Iran that reflect the period of Parthian rule of those regions, but Windfuhr also ascribes some of these to older Median influence.
