the accusative case means the direct object in the sentence structure. the dative case deals with the indirect objects. the nominative case refers to subjects which must agree grammatically with the verb; the genitive case refers to possession e.g.: she has an apple, but she gives me the apple of her friend because the apple belongs to her friend. sie hat einen Apfel. she has an apple. sie gibt mir den Apfel. she gives me the apple (or she gives the apple to me.) sie gibt mir den Apfel deiner Freundin, weil der Apfel ihrer Freundin gehört. she gives me the apple of her friend because the apple belongs to her friend.
one must understand english grammar to identify the proper english grammatically uses in order to understand the german grammar structure.
confused? dont be. it gets easier over time because its logical with a few exceptions. the biggest gripe i have with duolingo is its arbitrary uses of certain phrases, its heavy cognate emphasis and its indiscernible contexts of certain phrases. but enough about me.
I really wish the female bot voice was done better. More often than not, it sounds as if when recorded she was too close to the microphone and possibly has poor fitting dentures! I generally have to play her on tortoise to try and work out what she is saying. On THIS one she very clearly says hats einen Apfel, inserting the s, but says ha(t) on normal speed. Yes, I reported fault, but no way to indicate....in tortoise. Ah well, the man is beautifully clear.
a and an are not interchangeable. both are the indefinite article before a noun. one uses a in front of nouns which begin with a consonant. an is used in front of a noun, adjective or adverb, which begins with a vowel. a apple is incorrect. an apple is correct. a dog but an ostrich. a book but an orange. a wormy apple or an old apple. a tall ostrich but an awkward ostrich. an old book but a dirty dog. etc.
Yes, although that bit is something of a pun. They repeat the line a few times adding a word each time until you get the full sentence, which is 'Du hast mich gefragt' which means 'You have asked me.'
However, an intervening stage in building that sentence like that is 'Du hast mich' which sounds like 'Du hasst mich' which means 'You hate me.'
Sie hat den Apfel. "She has the apple." with the definite article implies that this is an apple that you have spoken about before, or at least one that is obvious to the listener from context.
Sie hat einen Apfel. "She has an apple.", on the other hand, uses the indefinite article and does not imply this -- the apple is instead considered new information at least for the listener.
The two sentences do not mean the same thing.
And there is no German word apfel, only Apfel (capitalised).
Because the apple is the direct object of the verb "have" -- it's the thing which is owned. So it has to be in the accusative case.
The word Apfel is masculine, so you need the masculine accusative form of the indefinite article here - which is einen.
ein is the masculine nominative form (e.g. ein Apfel liegt auf dem Tisch), or the neuter nominative/accusative form (e.g. ein Pferd steht vor der Tür / ich habe ein Pferd).
Why not Sie hat ein Apfel?
Because Apfel is (a) masculine and (b) the direct object of the verb haben (to have), so it has to be in the accusative case.
Thus you need the masculine accusative form einen of the indefinite article.
ein can be masculine nominative (wrong case), neuter accusative (wrong gender), or neuter nominative (wrong case and gender).
no context on if it is 'she' or 'they'.
Eh, what do you mean "no context"?
There's a -t at the end of the verb; that's the context you need to know that it's "she".
"they" verb forms end in -en.
sie hat = she has; sie haben = they have.
sie trinkt = she is drinking; sie trinken = they are drinking.
was taught "haben" doesnt change to akkusative.
Then you were taught wrongly.
haben most definitely takes a direct object in the accusative case.
(At least, when it's the main verb, in the meaning of "own, possess". Things are different if it's only a helping verb -- then case is assigned by the main verb.)
If i'm not mistaken einen Äpfel is singular.
You are mistaken. It's ein Apfel in the singular (and einen Apfel in the accusative case) -- no umlaut.
Äpfel with umlaut is plural -- die Äpfel in the nominative and accusative cases, and den Äpfeln with -n in the dative case.
den Apfel is accusative singular.
