What to expect?
Dutch is the mother tongue of millions of people in the Netherlands, Belgium and many inhabitants of former Dutch colonies such as Surinam and the Netherlands Antilles. People have been migrating to the Netherlands for centuries and over the years the Netherlands has become a multi-cultural society. Learning Dutch is not essential to survive in this country since a large part of the population either speaks or understands English; however, learning the basics might come in handy and the Dutch people will certainly appreciate it if you are able to hold a simple conversation in their language.
Dutch is the lingua franca; English is only used for clarification and explanation purposes.
