Anyone who says that
Dutch is German for German is wrong and wouldn't even recognise Dutch.
So unlike a lot of US, UK or other native English-speaking people think, Dutch is NOT German! Dutch may be a little simmular to German, but it's more closely related to English.
Dutch is a Germanian language, just like German and English. (french, italian, and spanish are romanian languages).
Dutch is more closely related to English on the grammar, but the vocab is more Germanish. Dutch is in between English and German, but still is a whole language on its own - it's NOT English and NOT German.
