Der Schuh ist in der Suppe?

[guyfefold]

Why does "der Suppe" translate to "that soup" and not "the soup"?

[GuyFain]

Der can be translated as either the or that, I think. It might be an error in the platform. You can always suggest!

[El_Lutzo]

The more interesting question is: Why the hack is the shoe in the soup?

[jonwizard]

Because soup is feminine, so it should be "die Suppe" unless you are using the dative form, in which case "der" is the female article. Almost all words ending in e are feminine.
