The Turkish alphabet reform (Turkish: Harf Devrimi or Harf İnkılâbı) is the general term used to refer to the process of adopting and applying a new alphabet in Turkey, which occurred with the enactment of Law No. 1353 on "Acceptance and Application of Turkish Letters" on 1 November 1928. The law was published in the Official Gazette on 3 November 1928, and came into effect on that day. With the approval of this law, the validity of the Ottoman Turkish alphabet, which was based on the Arabic script, came to an end, and the modern Turkish alphabet based on the Latin script was introduced.
The Turkish alphabet differs somewhat from the alphabets used in other languages that use the Latin script. It includes letters modified to represent the sounds of the Turkish language (e.g., Ç, Ö, Ü), including some unused in other languages (Ş, Ğ, contrasting dotted and undotted İ / I). The pronunciation of some letters in the Turkish alphabet also differs from the pronunciation of said letters in most other languages using the Latin alphabet. For example, the pronunciation of the letter C in the Turkish alphabet is /d͡ʒ/, the equivalent of J in English, whereas in the English alphabet, it represents the /k/ or /s/ sound.
