Criminal related to manager? (8)
I believe the answer is:
offender
'criminal' is the definition.
(I know that criminal can be written as offender)
'related to manager?' is the wordplay.
'related to' becomes 'of' (something 'of' something else is related to it).
'manager?' becomes 'fender' (someone who manages or fends for themselves).
'of'+'fender'='OFFENDER'
(Other definitions for offender that I've seen before include "Transgressor, lawbreaker" , "guilty party" , "One breaking rule" , "Delinquent" , "Culprit" .)
