Questions & Answers about Wir kaufen Möbel für die Wohnung.
Why is Möbel used here when 'furniture' is singular in English?
In English, 'furniture' is an uncountable noun, but in German, Möbel is plural. If you want to talk about a single piece of furniture, you would say ein Möbelstück. Because they are buying furniture in general, they just use the plural word without an article.
Why is the article die used after für?
The preposition für always requires the accusative case. Since Wohnung (flat/apartment) is a feminine noun, its accusative article is die. It looks exactly like the basic subject form, but it is actually in the accusative case to follow the rule for für.
The translation says 'are buying'. Why isn't there a German word for 'are' in this sentence?
German does not have an equivalent to the English continuous tense ('are buying', 'is running'). Whether you mean 'we buy' in general or 'we are buying' right now, you simply use the present tense: Wir kaufen.
Where does the word Wohnung come from?
Wohnung is the standard German word for both a flat and an apartment. It comes from the verb wohnen (to live or reside), so it literally translates to something like 'living space'.
