Now why is the dog eating an apple?
Why is hunden äter EN äpple wrong?
We have two different genders, common (en-words) and neuter (ett-words). "Äpple" is neuter.
Is there a list of en words and ett words?
Why is 'en hund äter ett äpple' wrong?
en hund = a dog, but the dog is determinate so it means hunden.
