Seemingly faultless learner (6)
I believe the answer is:
'learner' is the definition.
I don't 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 "New member (of religious order)" , "Probationary nun/monk" , "Beginner, trio" , "A beginner or student nun" , "Person in a religious order who has not yet taken final vows" .)
