High Quality Content by WIKIPEDIA articles! Ottoman Turkish (Turkish: Osmanl?ca or Osmanl? Türkçesi, Ottoman Turkish: ???? ??????? lisân-? Osmânî) is the variety of the Turkish language that was used as the administrative and literary language of the Ottoman Empire. It contains extensive borrowings from Arabic and Persian languages and was written in a variant of the Perso-Arabic script. As a result of this process, Ottoman Turkish was largely unintelligible to the less-educated lower and also rural members of society, who continued to use kaba Türkçe or "rough Turkish" which was much purer.
