'to walk home' = 'nach Hause gehen' That's just the way it is. Colloquially, you can say 'Ich gehe nach Haus' but I'd recommend to stick to the 'Hause'.
Because it is a phrase. If you say Ich gehe zu House, it means I go home. If you say Ich bin zu House, it means I am home. Hope this helps.
Could "I walk home" be accepted? If you walk, it has to be on foot, hasn't it?
If I were going home by car, can I say "Ich gehe zu Auto..."? If not, what would be the right way?
Yes, saying one walks home on foot is redundant. One can go home on foot but that particular translation is poor English grammar.
'Haus' is 'house,' and is a building built for permanent living in that is distinct from an apartment, hotel, or other living accommodations. A house is a house even if nobody lives there; it's just the building.
'Hause' is 'home,' and is a specific place someone or something lives. It doesn't even have to be a house to be your home. A rabbit's burrow is its home even though it's not a house.
Is "I go by foot to home" correct English? The "to home" part sounds weird to me...
No, you'd say 'to go home on foot' or just 'to walk home' in English. EDIT: by -> on
I was thinking that, too... But the software offered "I go by foot to home" as an alternative for translation.
I don't know what language that is but it doesn't look like English ;-) The software is far from being perfect. Speaking of bad English: my suggestion above should read 'to go home on foot' ;-)
Why I got wrong on "I go to house on foot." DL gave me answer "I go to my house on foot." where is "mein" in the sentence.
We do say "by car" but use "on foot." Sometimes "by" refers to a method but "on foot" notes that we are walking on our feet. When we want someone to stand up, we often say "get on your feet." Each language has its own quirks regarding prepositions.
I wonder how elect the preposition "to" or "at" from the different preposition für, um, an, auf, bei, mit, nach, zu. is there any rule for know about this?
This confuses me too. So far, I think we have to know every word along with its preposition as it is
I had to choose from given words. The only possible answer for me was I walk home on foot. As if I could walk any other way. Duo accepted it
It is 'on foot'. One only uses 'by' when referring to vehicles: as in, 'by car'.
