Is the usage correct - "occur/exist" coupled with "out of [place]"

Hello.

I've had a conversation with a native English speaker where we talked about certain literary works. It turned into a language discussion, and I asked him a question:
"Is 'speakwrite' an actual word that occurs out of Orwell's novel?", meaning "is it a real word, or the one made up as many others from Newspeak are?"

Somehow he believed I've made a typo and was asking whether it's a word out of Orwell's novel (which it is), so he said yes. It made for a funny misunderstanding, but I got worried there might be something about that sentence that I am missing.

I have the following questions:
1) Is the way I used the sentence correct, does it sound natural? If not, how should it be altered to carry the intended meaning?
2) Is it correct to say "does a word exist out/outside of Orwell's novel", and can the prepositions be used interchangeably? This couldn't have happened if I used "outside of" instead.
3) Is there a difference between "occur" and "exist" in the context of the phrase?

Thank you in advance.

1. No, it's not very natural. "Is that a real word, or is it one Orwell made up for his 'Newspeak'?"

2. "Outside of" is correct.

3. Use "exist." That's what you are asking. Does it exist?
