They open out for the novice (8)
I believe the answer is:
neophyte
'the novice' is the definition.
(neophyte is a kind of novice)
'they open out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'they'+'open'='theyopen'
'theyopen' anagrammed gives 'NEOPHYTE'.
'for' is the link.
(Other definitions for neophyte that I've seen before include "They open for a new convert" , "Novice of religious order, or new convert" , "Reformed character" , "Initiate" , "Beginner, novice" .)
