First novel (8)
I believe the answer is:
original
I believe this is a double definition.
'first' is the first definition.
('original' is associated in meaning with 'first')
'novel' is the second definition.
('original' can be similar in meaning to 'novel')
(Other definitions for original that I've seen before include "The first, not a copy" , "An oil rig (anag)" , "Creative, new in design" , "Never seen or performed before" , "First, earliest" .)
