Düsseldorf (UK: /ˈdʊsəldɔːrf/,  German: [ˈdʏsl̩dɔɐ̯f] (listen); often Dusseldorf in English sources; Low Franconian and Ripuarian: Düsseldörp [ˈdʏsl̩dœɐ̯p]; archaic Dutch: Dusseldorp) is the capital and second-largest city of the most populous German federal state of North Rhine-Westphalia after Cologne, as well as the seventh-largest city in Germany.[5] with a population of 617,280. At the confluence of the Rhineand its tributary Düssel, the city lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Regions with the Cologne Bonn region to its south and the Ruhr to its north. Most of the city lies on the right bank of the Rhine (as opposed to Cologne, whose city centre lies on the river's left bank). The city is the largest in the German Low Franconian dialect area (closely related to Dutch). "Dorf" meaning "village" in German, the "-dorf" suffix (English cognate: thorp) is unusual in the German-speaking area for a settlement of Düsseldorf's size.
