Avestan Lexicon

Avestan Lexicon is a complete, offline companion for reading the Avesta and studying the Avestan language — the sacred tongue of Zoroastrianism.

THE FULL AVESTA, OFFLINE
Read the entire corpus with no internet connection: the Yasna, the Gathas of Zarathustra, the Visperad, the Vendidad, the Yashts, the Khordeh Avesta, and the Fragments. Every verse is presented in Roman transliteration, in the original Din Dabireh (Avestan script), and in English translation, side by side.

A LIVING DICTIONARY
Look up thousands of Avestan words with translations, definitions, grammatical notes, and etymological detail. Search is diacritic-insensitive — type "asa" and find "aṣ̌a" — so you never have to hunt for the right accent. Tap any word in a verse to see its meaning instantly.

BUILT FOR STUDY
- Browse the dictionary A–Z or search in Avestan or English

COMPLETELY OFFLINE. COMPLETELY PRIVATE
The entire dictionary and scripture library are bundled inside the app. There is no account to create, no sign-in, no ads, and no tracking. Nothing you read or search ever leaves your device. It works the same on a plane, in an archive, or anywhere with no signal.

For students, scholars, Zoroastrians, and anyone drawn to one of the world's oldest religious traditions.
