I was just trying to remember all of the situations in which the word order for Swedish is different from English. I remembered that questions were quite a bit different, but this one is too and it's not a question. What is the reason for it not being: "Nu jag går hem"? Sorry! :c
Thanks for that observation. It is exactly what I came here for. Since Duo seems to always try to go for a close English translation, but they don't choose the one that seems to me to be the closest (i.e., "Now I'm going home"), it makes me wonder if the other form might be incorrect, even though it sounded fine to me.
thanks both of you for the support, but seems that i forget something here. as far as i remember the adverbs mostly need to come after the verb, isnt it? so i was thinking it should be jag går nu hem. also the 2nd question of mine is, why do we say Nu går jag hem? are we pointing something out, or are we emphasizing on something?
The main thing is that the verb has to go second (in main clauses that aren't questions). So in a main clause, unless you choose to put the adverb first, which is rare of course, it will go after the verb.
In går hem, hem is also an adverb (answering the question 'Where to?'). Describing the order among adverbs is probably the hardest part of word order. Jag går nu hem isn't totally wrong, but it's unnatural (it sounds formal in an odd way). hem should go first since it's more closely tied to the verb than nu is.
As for Nu går jag hem, the most neutral word order is to put the subject first. If you put the adverb first, that will get some extra focus.
I wrote a longer post about word order which may be helpful too: https://www.duolingo.com/comment/8970470
House and home are slightly different concepts in both Swedish and English: specifically, home (hem) is the place you live, and house (hus) is a type of building. (Incidentally, in Swedish, hus is a little broader than the English house, as it might also be used to refer to an apartment building for example.)
I am going to house now is actually not a valid English sentence either, if house is meant as a noun. (Even with the verb house, it would actually be very odd, as that verb really expects an object.) You'd have to say the house or my house.
I am going to my house now could be a valid translation, but Duo typically doesn't accept a less-literal translation where the more-literal one is also the closest, as in this case.
The rule is just that you have to have the verb in second place in all main clauses. So you can put the subject first or an adverbial first, but the verb must stay where it is.
The thing that is put first in the sentence is called the 'theme', 'topic', or 'foundation' of the sentence. This thing is what the sentence starts out from. The other part is called the 'rheme', 'comment', or 'focus' of the sentence.
So if you're saying a very ordinary sentence like this one, you can do it in two ways:
1.) Jag går hem nu 'jag' is the starting point of the sentence. You, the speaker, are a given in any situation where you are speaking. So it's natural to start talking about you and go on to say what you're going to do.
2.) Nu går jag hem In this version, 'nu' is the starting point. The idea of now is of course also always a natural place to start. Here you're starting out from where you are in time, and then saying what will happen at this point in time.
In this specific example, the difference between the two sentences will be very small. But the difference is not in focus on verb vs subject. If you want to stress one of those, you have to put stress on that word when speaking.
