Young Avestan is a form of the Avestan language, which is the liturgical language of the Zoroastrian scriptures. It is primarily used in the Yasna texts, composed around the 5th century BCE. Young Avestan reflects a more recent stage of the language compared to Old Avestan, showing changes in grammar and vocabulary. The language is significant for understanding the development of Zoroastrianism and its religious practices. Young Avestan texts include hymns, prayers, and rituals, providing insights into the beliefs and values of ancient Persian culture. Its study helps scholars trace the evolution of Indo-Iranian languages.
