Novel in the earliest stage of development (8)
I believe the answer is:
germinal
'in the earliest stage of development' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for germinal that I've seen before include "Relating to earliest stages of development" , "Malinger in the earliest stage of development" , "Novel by Zola; in an early stage of development" , "Rudimentary" , "a month after the French Revolution" .)
