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.

While this is kind of fun, it’s also kind of frustrating. Like when Merriam Webster tries to define a word for me by using the word. Frustrating: having a quality or qualities that frustrates.

Hippopotamus comes from the Greek words hippos (horse) and potamos (river). So literally "river horse".

So this is why Indonesian names for hippo, sea urchin and seal are weird af. They are actually direct translation from their dutch names!
