I have bought and read the entire decalogue of the Thomas covenant series. The first 2 trilogies were prime fantasy. The final quadrilogy probably deserves a re-read but it wasn't quite at the same level on the first read for me as the others.
It's the only book that I can remember that has sent me scrambling for a dictionary as the sentences contained words whose meaning could not be discerned by inference.
"The surquedry of the Elohim was their downfall", for instance.
I've been reading history books lately, and my ebook feature "look up selected word in dictionary or Wikipedia" is such a useful little thing. I wish I'd had something similar in the 80s (the convenience, I know I could get a dictionary)
A built-in pronunciation guide would also have been very appealing to this 80s bookworm.
Although I absolutely loved the first two chronicles, I could not get into the last chronicles at all. I read the first 1.5 books of those and gave up.
Part of that is the extreme verbiage, as you point out. Really breaks the flow when you're reaching for a dictionary three times a page. I also frankly just didn't like anyone at all in the last chronicles, and stopped caring. But maybe that's just because of all the dictionary lookups!
