آذری یا زبانِ باستانِ آذربایجان

A book about the ancient Azerbaijani language, its grammar and slang, and the roots of the language. The author is the only writer after Ferdowsi (author of the famous Shahnameh, or Book of Kings) to use the pure Persian language, without incorporating Arabic. His writings are vital to linguists and scholars whose goal is to analyse and understand the real Persian language.
