Translation:The child plays with the bear's red object.
It is "en rød genstand" but, like with definite articles, after a possessive pronoun of the genetive the adjective always uses its "e-form"
Sorry, i looked it up, but it served only to confuse even more-- what does genetive mean in this context?
I got "the child plays with the bears red item". I have used 'item' in the past for genstand before, and I could have sworn it was accepted..
