In Ottoman Turkish the city was known with various names, among which were en:Kostantiniyye (قسطنطينيه) (replacing the suffix -polis with the Arabic nisba), en:Dersaadet (در سعادت) and Istanbul (استانبول). Names other than Istanbul gradually became obsolete in Turkish, and after Turkey's transition to Latin script in 1928, the city's Turkish name attained international usage.
