Paris

No big surprise with this one (don't pronounce the 's' in French), but a few side notes and snippets of information:

• Paris was known as Lutèce (Lutetia) under Roman occupation, but takes its name from the Parisii celtic tribe that inhabited the region before the Romans
• It is nicknamed la ville-lumière (city of lights), supposedly both for its center role in the French cultural life and its famous street-lighting
• It is also referred to as Paname, an early-20th century slang term that has recently been revived by the young generation
  
• It's also sometimes referred to as la ville aux cent villages (the hundred-village city), la cité de l'amour (the city of love) or, modestly, la plus belle ville du monde (the most beautiful city in the world)
• Parisians are les Parisiens, also pejoratively called Parigots (pronounced pa-ree-go) by jealous non-Parisians
• Its often-mocked soccer team is PSG, which stands for Paris Saint-Germain
