I've fully succumbed to my inclination to make up words as I see fit. I know enough Greek and Latin roots to engineer a completely logical word when I can't think of the appropriate terminology.

I guess my question is:
Is this "literary license" proper?

I guess there isn't an established code of conduct concerning use of the English language. The government doesn't require toddlers to sign waivers as they utter their first words. There aren't uniformed agents that jail chronic offenders. But I like to think that we philologists and bibliophiles follow sets of invisible, unwritten rules to remain as coherent as possible. Just my two drachmai.
