Turkish name of Constantinople, a corruption of Greek phrase eis tan (ten) polin "in (or to) the city," which is how the local Greek population referred to it. Picked up in Turkish 16c., though Turkish folk etymology traces the name to Islam bol "plenty of Islam." Greek polis "city" has been adopted into Turkish as a place-name suffix as -bolu.[Istanbul etymology, Istanbul origin, 英语词源]
