I apologise if this has been raised before, but I was wondering if there were any rules that govern the use of prefixes and suffixes?
I believe there are several newspeak (as in 1984-like) words that have been adopted into the language, can the newspeak treatment be applied to any word, or are there some conventions to follow apart from just the appearance in the dictionary?
Can you, more specifically, turn any noun into an adjective?

hmm that's quite rambling. many apologies again, I'm not good at being succinct


It's staring you in the face.
