Why is "ein Mädchen" correct? So... I was learning the very first basics and I stumbled onto an example that said: "ein Mädchen". As far as I'm concerned "ein" is used for masculine, while "eine" is used for feminine. But if "Mädchen" means "girl/young woman", which is a feminine noun, then shouldn't it be "eine Mädchen" instead? Thanks beforehand.
