Avestan is the old language of the Zoroastrian religion, which is a term referring to the Parsi’s religion. This is a language in which the sacred texts of Zoroastrianism called Avesta are written. Avesta is a collection comprising of hymns, prayers, rituals, and philosophy attributed to prophet Zarathustra.

Avestan is an ancient Indo-Iranian language that existed in present-day Iran about two thousand years ago. The language has many similarities with old Iranian language and also close ties with Sanskrit which is the ancient language of Hindu sruthis.

Avesta is written in the Avestan script, an ancestor of the modern Aramaic alphabet. The script is a collection of symbols that represent the vowels and consonants.

Today, it is commonly thought of as a dead language because of its oldness and few speakers. Nevertheless, scholars and priests in the Parsi community have continued to study and preserve the Avesta and its language for their religious and historical purposes.

Avestan was an old Iranian language, which was used for writing the sacred books of Zoroastrianism called Avesta. These include the philosophy of the religion as well as songs, prayers and rights that make up the Bible of the religion.

Hence, the Parsis should neither speak nor understand Avestan at present. Initially, the language gave birth to Middle Persian which later evolved into Modern Persian (Farsi). Nowadays, most Parsis speak either Gujarati or English, depending on where they reside.

However, Avestan is very important for religion but Zoroastrian scholars and worship masters, who know it the best.
