"Gehst du nach Hause oder bist du schon zu Hause?"

Translation: Are you going home or are you already at home?

[cekuna]

I am confused about usage of "nach" and "zu" since the definition of "zu" was given as "to/towards" earlier. How does "zu" mean "at" here? And why is it Hause but not Haus?

[PatriciaJH]

These are idioms, and Hause means home, while Haus means house.

Zu Hause means at home; nach Hause means towards home, moving towards home.

Hause is the old dative case of Haus.

But zu Hause and nach Hause are fixed expressions and don't necessarily refer to a house.

Why ‘do you go home or are you already at home?’ is not correct?

[tomerisrael]

Should accept "do you go home"

[KyleJohnso462836]

Are you going home or are you home?

[BenjaminIs818508]

These ZU,NACH,BEIM makes me ❤❤❤❤❤❤❤ nervous. Grrrrrrrrr.

[Shimerab]

Could it also be Are you going to the house or are you already at home?

[Randonneur3]

Duo has previously not insisted on the english present continuous. 'Do you go..' is Duo-speak. Just saying.

[Nweech]

Are you going home or are you already there?

How do Hause and Heim differ?

[igelchen]

There's no difference between "nach Hause" and the adverb "heim". But be careful, "Heim" as a noun tends to (but doesn't have to) refer to an old people's home, a children's home or even an asylum rather than someone's home.
"Ich gehe heim" = "Ich gehe nach Hause" - "I'm going home"
"Er ist in einem (or just "im" instead of "in einem") Heim aufgewachsen" - "He grew up in a children's home"
"Ich bin zuhause/zu Hause" - "I'm at home". This could also be "Ich bin daheim", but my understanding is that this is mainly used in the south (southern Germany, Austria and Switzerland).
"Das ist mein Zuhause" - ("Das ist mein Heim", if you must use it) = "this is my home" ("Heimat", if you're talking about a region, state, country, etc., and there are other options which I just can't think of right now).

I said "are you going home or already at your house" mindlessly, but, should It be accepted?

[Horacio293080]

there aren't enough words in this level 3 task, you should have to transcribe War and Peace by Leo Tolstoy in German, that should be adequate
