* In common language the
Genitive of the substantival possessive pronoun is not
used. There is another form of a possessive that could
be used (der eurige, die eurige, das eurige), but it sounds
really antiquated. If you want to form a Genitive of eure
it is mostly done like in English.
Das
ist der Schlüssel von eurem (Auto
etc.).
This is the key to yours. (car etc.)
Example:
die Schachtel (= box) possessed object => feminine,
singular
Ich sehe
eure, aber unsere nicht.
I see yours but not ours.
Example:
das Kleid (= dress) possessed object => neutral,
singular
Du kannst
mit eurem hingehen.
You can go with yours.
Example:
die Häuser (= house) possessed object =>
neutral, plural
Ich sehe
eure, aber ihre nicht.
I see yours but not hers.
