Please pardon my lack of understanding for major English Language concepts, I'll be using layman's terms.
Now, I've encountered this issue in the past while writing. Consider this text:
That was about the best he could do, information density wise.
You can replace information density with loads of other ideas which must be described using two nouns, i.e., refresh rate, focal length, cooking time, etc.
The problem is, "wise" in that sentence was supposed to be used in its suffix form, and it too could be replaced with loads of other descriptive suffixes.
How do I add a descriptive suffix to an idea described with two inseparable words?
Information density -wise?
