Hopefully it has become clear to you that Dutch is not as difficult as many people say it is. The grammar is second to English in its simplicity, the spelling is very regular, and we share a large number of Germanic words. The advantages of even a little knowledge of Dutch are obvious.
Of course it will take a longer time to gain a complete mastery of the language. But a working knowledge – enough to read newspapers, chat with Dutch people on the street, in shops or at work, or even read a Dutch novel – is well within the grasp of any foreigner spending a few years here and who has a few hours a week to spare for language study plus some opportunity to put it into practice.
