Naive in wanting skills? (7)
I believe the answer is:
artless
This clue is a double definition.
'naive' is the first definition.
(similar in meaning)
'wanting skills?' is the second definition.
(without skill or craft)
'in' acts as a link.
(Other definitions for artless that I've seen before include "Clumsy and uncaring" , "Free from cunning" , "Without pretension" , "Simple and natural in manner" , "Naive - unskilful" .)
