I said कहानी किताब में है, but that was rejected. Why?
That would be "The story is in the book."
Is it also ok to say "इस किताब में एक कहानी है" ?
No. That'll be translated in English as "there is a story in THIS book."
किस तरह की कहानी? कहानी... घर घर की? =O
I wrote किताब में एक कहानी है but it was wrong. Why?
It is right. Report if you see the sentence again.
