Pazend
The use of the Avestan alphabet to write Middle Persian required the addition of one symbol to the Avestan alphabet: This character, to represent the /l/ phoneme of Middle Persian, had not previously been needed.Following the fall of the Sassanids, after which Zoroastrianism came to be supplanted by Islam, Pazend lost its purpose and soon ceased to be used for original composition.In the late 11th or early 12th century, Indian Zoroastrians (the Parsis) began translating Avestan or Middle Persian texts into Sanskrit and Gujarati."Pazand texts, transcribed phonetically, represent a late and often corrupt Middle Persian pronunciation, and so present their own problems.These prefatory prayers are invariably written in Pazend because of the need for "accurate" pronunciation.
