Immaculate paths finally free of grass (8)
I believe the answer is:
spotless
'immaculate' is the definition.
('spotless' can be a synonym of 'immaculate')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spotless that I've seen before include "Immaculate" , "Perfect" , "Without a mark, completely clean" , "totally innocent" , "Immaculately clean" .)
