Strangely genuine female without experience (7)
I believe the answer is:
ingenue
'female without experience' is the definition.
'strangely genuine' is the wordplay.
'strangely' is an anagram indicator.
'genuine' anagrammed gives 'INGENUE'.
(Other definitions for ingenue that I've seen before include "Naive young woman" , "She's artless" , "Unsophisticated young female" , "young woman lacking experience" , "Unsophisticated girl" .)
