Turkish is a Turkic language with about 70 million speakers in Turkey and in 35 other countries, including Australia, Austria, Azerbaijan, Belgium, Bulgaria, Canada, Cyprus, Denmark, El Salvador, Finland, France, Georgia, Germany, Greece, Honduras, Iran, Iraq and Israel.
Until 1928, Turkish was written with a version of the Perso-Arabic script known as the Ottoman Turkish script. In 1928, as part of his efforts to modernise Turkey, Mustafa Kemal Atatürk issued a decree replacing the Arabic script with a version of the Latin alphabet, which has been used ever since.
