Dutch is a language that people talk in the Netherlands, a country where you can smoke pots, and in half part of Belgium and in some islands and in south Africa. For a lot of languages, they have created a website where you can learn heaps of languages for free having fun, the website name is " duolingo" I recommend this website also to kids and I suggest their parents let them playing with it. You need to create an account and LEARN, ' a bit every days is the motto'
