Ottoman Turkish /ˈɒtəmən/, or the Ottoman language (لسان عثمانى‎‎ Lisân-ı Osmânî) (also known as تركچه‎ Türkçe or تركی‎ Türkî, "Turkish"), is the variety of the Turkish language that was used in the Ottoman Empire. It borrows extensively from Arabic and Persian, and was written in the Ottoman Turkish alphabet. During the peak of Ottoman power, Persian and Arabic vocabulary amounted for up to 88% of its vocabulary, while words of Arabic origins heavily outnumbered native Turkish words.
