What you’ll actually hear as a visitor

  • In central Prague (tourist areas, hotels, many restaurants and museums), a lot of people also speak English, especially younger Czechs and service staff.
  • You may occasionally encounter German or other languages (like Ukrainian or Vietnamese) due to minority communities and tourism, but Czech is what you will see on signs, tickets, and most menus.

If you’re traveling there

  • Knowing a few basic Czech phrases (like “Dobrý den” for hello or “Děkuji” for thank you) is appreciated, even though you can generally get by in English in the main tourist parts of Prague.
