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.
Culture of the Ottoman Empire
Ottoman culture evolved over several centuries as the ruling administration of the Turks absorbed, adapted and modified the cultures of conquered lands and their peoples. There was a strong influence from the customs and languages of Islamic societies, notably Arabic, while Persian culture had a significant contribution through the heavily 
Persianized Seljuq Turks, the Ottomans' predecessors. Despite newer added amalgamations, the Ottoman dynasty, like their predecessors in the Sultanate of Rum and the Seljuk Empire, were thoroughly Persianised in their culture, language, habits and customs, and therefore, the empire has been described as a Persianate empire." Throughout its history, the Ottoman Empire had substantial subject populations of Orthodox subjects, Armenians, Jews and Assyrians, who were allowed a certain amount of autonomy under the confessional "millet" system of Ottoman government, and whose distinctive cultures enriched that of the Ottoman state.
