The Manichaean script is an abjad-based writing system rooted in the Semitic family of alphabets and associated with the spread of Manichaeism from southwest to central Asia and beyond, beginning in the third century CE. It is a variant of the Syriac script. It bears a sibling relationship to early forms of the Pahlavi scripts, both systems having developed from the Imperial Aramaic alphabet, in which the Achaemenid court rendered its particular, official dialect of Aramaic. Unlike Pahlavi, the Manichaean script reveals influences from the Sogdian alphabet, which in turn descends from the Syriac branch of Aramaic. The Manichaean script is so named because Manichaean texts attribute its design to Mani himself. Middle Persian is written with this alphabet.
The Iranologist Desmond Durkin-Meisterernst notes that the Manichaean script was mainly used to write numerous Middle Iranian languages (Manichaean Middle Persian, Parthian, Sogdian, Early New Persian, Bactrian) and Old Uyghur (a Turkic language). The Manichaean script is closely related to the Palmyrene alphabet of Palmyrene Aramaic and the Estrangelo script of Syriac.
