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.

These court categories were not, however, wholly exclusive: for instance, the Islamic courts, which were the Empire's primary courts, could also be used to settle a trade conflict or disputes between litigants of differing religions, and Jews and Christians often went to them to obtain a more forceful ruling on an issue. The Ottoman state tended not to interfere with non-Muslim religious law systems, despite legally having a voice to do so through local governors. The Islamic "Sharia" law system had been developed from a combination of the Qur'an; the Hadīth, or words of the prophet Muhammad; "ijmā'", or consensus of the members of the Muslim community; qiyas, a system of analogical reasoning from earlier precedents; and local customs. Both systems were taught at the Empire's law schools, which were in Istanbul and Bursa.
