The Armeno-Turkish alphabet is a version of the Armenian alphabet sometimes used to write Ottoman Turkish until 1928, when the Latin-based modern Turkish alphabet was introduced. The Armenian script was not just used by ethnic Armenians to write the Turkish language, but also by the non-Armenian Ottoman Turkish elite. An American correspondent in Marash in 1864 calls the alphabet "Armeno-Turkish", describing it as consisting of 31 Armenian letters and "infinitely superior" to the Arabic or Greek alphabets for rendering Turkish.
