Ottoman Turkish is as essential for accessing the orderly and rich records of the Sublime State as it is for reaching the non-official works of our religious, literary, cultural, social, and scientific heritage. Every work, inscription, and tombstone written in Ottoman Turkish from the end of the 13th century onwards carries the character of a treasure left by our ancestors to the children of these lands. Ottoman Turkish is the key to such a treasure. The Hayrat Foundation, which has carried out many studies since its establishment to ensure that this historical and cultural treasure reaches present generations, has accepted it as a duty to introduce this valuable treasure to our people through the Ottoman Turkish courses it organizes across Turkey. The book in your hands is a continuation of the Ottoman Turkish books that are the result of this sacred duty.
