I came across an amazing aria called "Der Hölle Rache kocht in meinem Herzen". It is sung by the Queen of the Night in The Magic Flute (Die Zauberflöte), an opera by Mozart.
I don't understand why the phrase "in meinem Herzen" is used here.
- Since Herzen is the plural form of das Herz, is it implying that the Queen of the Night has multiple hearts?
- Additionally, I'm fairly confident that this phrase is in the Dativ case. If so, why is meinem used instead of meinen?
edit: here's what I thought: this phrase is Dativ and Herzen indicates plural, so it is similar to "mit meinen Kindern". I didn't see why "meinem" is used instead, but that now I know that Herzen is singular Dativ, the phrase makes more sense. Thanks!
PS: I'm a beginner in learning German. I hope that this question doesn't sound too strange.
