Avestan alphabetThe Avestan alphabet (Middle Persian: transliteration: dyn' dpywryh, transcription: dēn dēbīrē, دین دبیره) is a writing system developed during Iran's Sasanian era (226–651 CE) to render the Avestan language. As a side effect of its development, the script was also used for Pazend, a method of writing Middle Persian that was used primarily for Zend commentaries on the texts of the Avesta. In the texts of Zoroastrian tradition, the alphabet is referred to as "the religion's script" (dēn dibīrih in Middle Persian and din dabireh in New Persian).
Pahlavi scriptsPahlavi is a particular, exclusively written form of various Middle Iranian languages. The essential characteristics of Pahlavi are: the use of a specific Aramaic-derived script; the incidence of Aramaic words used as heterograms (called uzwārišn, "archaisms"). Pahlavi compositions have been found for the dialects/ethnolects of Parthia, Persis, Sogdiana, Scythia, and Khotan. Independent of the variant for which the Pahlavi system was used, the written form of that language only qualifies as Pahlavi when it has the characteristics noted above.
ParsisParsis (ˈpɑrsiː) or Parsees are an ethnoreligious group of the Indian subcontinent adhering to Zoroastrianism. They are descended from Persians who migrated to Medieval India during and after the Arab conquest of the Persian Empire (part of the early Muslim conquests) in order to preserve their Zoroastrian identity. The Parsi people comprise the older of the Indian subcontinent's two Zoroastrian communities vis-à-vis the Iranis, whose ancestors migrated to British-ruled India from Qajar-era Iran.
AvestaThe Avesta (ə'vɛstə) is the primary collection of religious texts of Zoroastrianism, composed in the Avestan language. The Avesta texts fall into several different categories, arranged either by dialect, or by usage. The principal text in the liturgical group is the Yasna, which takes its name from the Yasna ceremony, Zoroastrianism's primary act of worship, and at which the Yasna text is recited. The most important portion of the Yasna texts are the five Gathas, consisting of seventeen hymns attributed to Zoroaster himself.
Middle PersianMiddle Persian or Pahlavi, also known by its endonym Pārsīk or Pārsīg (𐭯𐭠𐭫𐭮𐭩𐭪) in its later form, is a Western Middle Iranian language which became the literary language of the Sasanian Empire. For some time after the Sasanian collapse, Middle Persian continued to function as a prestige language. It descended from Old Persian, the language of the Achaemenid Empire and is the linguistic ancestor of Modern Persian, an official language of Iran, Afghanistan (Dari) and Tajikistan (Tajik).
