Rules for accusative case
What is the accusative case?
This is the noun that is the receiver of the action, ie. what the verb acts on like Die Frau kauft den Computer (Der Computer changes to Den Computer.)
Both the definite article(the/that) and indefinite article(a/an) change only for masculine nouns. Here is the general overview
Definite: den Mann | die Frau | das Kind | die Gäste
Indefinite: einen Mann | eine Frau | ein Kind | - Gäste
Negative: keinen Mann | keine Frau | kein Kind | keine Gäste
Possessive: meinen Mann | meine Frau | mein Kind | meine Gäste
Actually, in the case of "Jungs," 'den' implies the dative case. Think back to your first German lessons: "Wie geht es DIR?" "Es geht MIR gut!" As you can see, the construction "es gehen" goes with the Dative case. This case is no different.
Thank you! How to explain the sentence of "Den Jungs geht es gut"? "Den" implies accusative case, however it seems that "Jungs" is the subject.
Not necessarily, there are sentences without objects as well as sentences with Dative objects.
Isn't there some rule about when the sentence is a sentence like an equal sign (ie: Joe is a man), then the accusative is NOT used? (so then "Joe ist EIN Mann") I think this applies to "sein" and a few other verbs, but I'm not sure. Does anyone know if this is true and, if so, what those other verbs are? Thanks!
This is quite late, and I'm not well versed in German grammar, but here goes: In English, "man" in that sentence is not a direct object, but a predicate nominative; the accusative case is the same as a direct object English, which is most likely why "ein" is used instead of "einen."
