Languages of the Ottoman Empire
The language of the court and government of the Ottoman Empire was Ottoman Turkish, but many other languages were in contemporary use in parts of the empire. Although the minorities of the Ottoman Empire were free to use their language amongst themselves, if they needed to communicate with the government they had to use Ottoman Turkish.
Turkish Cypriots
The Turkish language was introduced to Cyprus with the Ottoman conquest in 1571 and became the politically dominant, prestigious language, of the administration. In the post-Ottoman period, Cypriot Turkish was relatively isolated from standard Turkish and had strong influences by the Cypriot Greek dialect. The condition of coexistence with the Greek Cypriots led to a certain bilingualism whereby Turkish Cypriots' knowledge of Greek was important in areas where the two communities lived and worked together.
