Reprobate will have nothing to do with Dickensian character (5,5)
I believe the answer is:
black sheep
'reprobate' is the definition.
(black sheep is a kind of reprobate)
'will have nothing to do with dickensian character' is the wordplay.
I cannot quite see how this works, but
'character' could be 'he' (he is a kind of character) and 'he' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for black sheep that I've seen before include "Dodgy character" , "Source of family shame" , "one rejected by family" , "One regarded as disgrace to family" , "Person in disgrace" .)
