I wrote, I speak with him. Why was this marked wrong? What is the difference?
Ok, I guess "my future car" is a definite noun and thats why we use fremtidige instead of fremtidig?
Yes, "min fremtidige karriere" is definite.
what is a definite noun?
"The dog" is definite - it refers to a specific dog. "A dog" is indefinite.
Why is it 'karriere' considered a plural in this sentence?
It isn't. "Min" indicates a singular noun which is common (an "n-word"). See what MMuhr wrote for the reason why "fremtidig" is in its e-form
wait what? why is fremtidige and not fremtidigt?
