A pure beginner? (6)
I believe the answer is:
novice
'beginner?' is the definition.
(I know that beginner can be written as novice)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for novice that I've seen before include "Probationary monk/nun" , "Noob" , "apprentice" , "New starter" , "Salvage" .)
