How Istanbul go its name

[Dena]

This is a great book to read after finishing the thriller, The Historian. Interesting tidbit:

"Constantinople, though the Ottomans would continue to refer to it officially by the Arabic name Konstantiniyye, [how] evolved into everyday Turkish into Istanbul is still unclear. The word may be a simple corruption of Constantinople, or it could be derived quite differently. Greek speakers would refer to Constantinople familiarly as polis, the city. A man going there would say he was going eis tin polin - 'into the city' - which could have been interpreted to Turkish ears as Istanbul.
