Imagine you are going to ask someone about the source of an idea to do something. Which one of the following sentences does not have a correct structure or construction?
- Where did you get the idea of your book?
- How did you come to the idea of writing this book?
When I google the bold verbs above, I receive some hits, but I doubt if they are used in normal English! (Although, they are exactly the way we say in our language.)
Bringing up this question, I need to know whether these verbs are natural and idiomatic or not?
