Dīwān ul-Lughat al-Turk

Dīwān ul-Lughat al-Turk is a work in Arabic by Mahmud al-Kashgari, first published in 1072. It is the earliest known comprehensive dictionary of Turkic languages, assembled to record and organize the languages of the Turkic world as they were known at the time. Rather than telling a story, the book presents a structured view of language, making it both a linguistic reference and a historical document.

It is best suited to readers interested in linguistics, the history of languages, and early scholarly attempts to describe living speech in a systematic way. What stands out is its scope and its place as a foundational dictionary for Turkic languages. If you like historical reference works, language study, or books that sit between documentation and analysis, this one fits that lane well.
