Discover code’s cryptic in part (6)
I believe the answer is:
descry
'discover' is the definition.
(thesaurus)
'code's cryptic in part' is the wordplay.
'in part' indicates the answer is hidden within the clue.
'DESCRY' is hidden within 'codes cryptic'.
(Other definitions for descry that I've seen before include "Perceive - make out" , "Catch sight of (poetic)" , "See" .)
