Been meaning to do this for a while - I've just uploaded a wordlist for Song of Scarabaeus to my website.
I tend to get a little disheartened to find a glossary in the back of novels. Even worse, a cast of characters, which is just a warning there are too many to keep track of. So I'm glad this list doesn't appear in my book. I would hope that the words I use are either self-explanatory in context or that I give sufficient explanation. This is just for reference.
It seems the words fall into four categories:
Words that sound made-up but aren't (lag, shiv, slater)
Real words that I've appropriated or redefined - consider them futuristic mutations (such as spur, drub, leash, the Reach)
Classic sci-fi words that someone else made up, or made up something similar (gravplating, magkey, nodespace, wet-teck, medfac)
Invented words (biocyph, nanofinds, neuroxin)
