Languages of the Ottoman Empire
The Ottomans had three influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except in Albania, Bosnia, and various Aegean Sea islands; Persian, initially used by the educated in northern portions of the Ottoman Empire before being displaced by Ottoman Turkish; and Arabic, used in southern portions of the Ottoman Empire; Arabic was spoken mainly in Arabia, North Africa, Mesopotamia and the Levant. Throughout the vast Ottoman bureaucracy Ottoman Turkish language was the official language, a version of Turkish, albeit with a vast mixture of both Arabic and Persian grammar and vocabulary.
Loanword
During more than 600 years of the Ottoman Empire, the literary and administrative language of the empire was Turkish, with many Persian, and Arabic loanwords, called Ottoman Turkish, considerably differing from the everyday spoken Turkish of the time. Many such words were exported to other languages of the empire, such as Albanian, Bosnian, Bulgarian, Croatian, Greek, Hungarian, Ladino, Macedonian, Montenegrin and Serbian. After the empire fell after World War I and the Republic of Turkey was founded, the Turkish language underwent an extensive language reform led by the newly founded Turkish Language Association, during which many adopted words were replaced with new formations derived from Turkic roots. That was part of the ongoing cultural reform of the time, in turn a part in the broader framework of Atatürk's Reforms, which also included the introduction of the new Turkish alphabet.
