Rent a bar for a change, deviating from type (8)
I believe the answer is:
aberrant
'deviating from type' is the definition.
(something aberrant is divergent or deviant)
'rent a bar for a change' is the wordplay.
'for a change' indicates anagramming the letters.
'rent'+'a'+'bar'='rentabar'
'rentabar' with letters rearranged gives 'ABERRANT'.
(Other definitions for aberrant that I've seen before include "Divergent from the normal" , "Deviating from what is accepted" , "Transgressing" , "Departing from type" , "Departing from accepted standard" .)
