Leopard: Lazy Horse (luipaard)
I’ve looked it up and apparently leo is lion and part is leopard or panther. So it’s a lion leopard. English and Dutch have the same etymology, and German too, all your examples are the same in German.
Are you implying that the word for leopard is compounded from the word for leopard??? How did they get the first word for leopard if they didn’t have a word for leopard???
Correction: it’s male leopard. It surprised me as well. It’s ultimately from Indo-Iranian origin.
