Dull epic novel is extremely clear (8)

I believe the answer is:
pellucid
'extremely clear' is the definition.
'pellucid' can be an answer for 'clear' (similar in meaning). I'm not certain of the 'extremely' bit.
'dull epic novel' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'dull'+'epic'='dullepic'
'dullepic' with letters rearranged gives 'PELLUCID'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for pellucid that I've seen before include "Very clear, totally transparent" , "Translucent" , "Translucently clear" , "Absolutely crystal clear" , "Crystal-clear" .)
