<P> The modern Turkish name for the city , İstanbul , derives from the Greek phrase eis tin polin ( εἰς τὴν πόλιν ) , meaning `` into the city '' or `` to the city '' . This name was used in Turkish alongside Kostantiniyye , the more formal adaptation of the original Constantinople , during the period of Ottoman rule , while western languages mostly continued to refer to the city as Constantinople until the early 20th century . In 1928 , the Turkish alphabet was changed from Arabic script to Latin script . After that , as part of the 1920s Turkification movement , Turkey started to urge other countries to use Turkish names for Turkish cities , instead of other transliterations to Latin script that had been used in the Ottoman times . In time the city came to be known as Istanbul and its variations in most world languages . </P>
