In Middle Persian, the name is , Zardu(x)št, in Parthian Zarhušt in Manichaean Middle Persian Zrdrwšt, in Early New Persian Zardušt, and in modern (New Persian), the name is , Zartosht.The name is attested in Classical Armenian sources as Zradašt (often with the variant Zradešt). The most important of these testimonies were provided by the Armenian authors Eznik of Kolb, Elishe, and Movses Khorenatsi. The spelling Zradašt was formed through an older form which started with *zur-, a fact which the German Iranologist Friedrich Carl Andreas (1846–1930) used as evidence for a Middle Persian spoken form *Zur(a)dušt.
