"If you could please answer this question, it would surely settle a huge debate:
In English, people from Paris are Parisians. People from Rome are Romans. What do you call people from Prague?"
Although neither dictionaries nor the spell check on my computer recognise it, one can come across the word "Praguers", especially among the expat community in Prague. In Czech the word is Prazan - or Prazak in colloquial speech - so it would make sense to have a short, one-word term in English, too. On Radio Prague we usually refer to them as Prague citizens. But we'd like to know what you, the listeners, think about the terms - which one do you prefer? Please, let us know...

Of course, it doesn't sound as familiar to most English-speakers as "Berliner" or "Parisian", but "Praguer" is the word that you typically see, for example, in guide books to Prague:

"So all those fancy restaurants and stylish bars are out of reach of the majority of Praguers, their custom confined to expats, gangsters, ...".
