Translation:There is no radio in the house.
I wrote "there isn't a radio in the house". It should have been accepted but was not. Unless I am missing something, grammatically it is correct.
Shouldn't "I don't have a radio at home" be accepted as well?
Could you also say : "The house has no radio." ?
In your sentence, "house" is the topic of the sentence, so it would be written as "집은 라도오가 없어요." The meaning doesn't change of course, it's just a grammatical difference.
