The Turkish alphabet () is a Latin-script alphabet used for writing the Turkish language, consisting of 29 letters, seven of which (Ç, Ğ, I, İ, Ö, Ş and Ü) have been modified from their Latin originals for the phonetic requirements of the language. This alphabet represents modern Turkish pronunciation with a high degree of accuracy and specificity. Mandated in 1928 as part of Atatürk's Reforms, it is the current official alphabet and the latest in a series of distinct alphabets used in different eras.
The Turkish alphabet has been the model for the official Latinization of several Turkic languages formerly written in the Arabic or Cyrillic script like Azerbaijani (1991), Turkmen (1993), and recently Kazakh (2021).
The earliest known Turkic alphabet is the Orkhon script, also known as the Old Turkic alphabet, the first surviving evidence of which dates from the 7th century. In general, Turkic languages have been written in a number of different alphabets including Uyghur, Cyrillic, Arabic, Greek, Latin, and some other Asiatic writing systems.
Ottoman Turkish was written using a Turkish form of the Arabic script for over 1,000 years. It was poorly suited to write works that incorporated a great deal of Arabic and Persian vocabulary as their spellings were largely unphonetic and thus had to be memorized. This created a significant barrier of entry as only highly formal and prestige versions of Turkish were top heavy in Arabic and Persian vocabulary. Not only would students have trouble predicting the spellings of certain Arabic and Persian words, but some of these words were so rarely used in common speech that their spellings would not register in the collective conscious of students. However, it was much better suited to the Turkish part of the vocabulary. Although Ottoman Turkish was never formally standardized by a decree of law, words of Turkic origin largely had de facto systematic spelling rules associated with them which made it easier to read and write.
