"The girl has a grandfather."
Translation:Das Mädchen hat einen Großvater.
Shouldn't we use genitive (indicates possession or relationship) in this case?
The girl HAS (she has, possession) a grandfather.
Das Mädchen hat EINES Großvater.
p.s. I did a little checking before posting and found out that this is how genitive should be like (I guess hahaha):
Der Großvater des Mädchens.
