Solicitor (6)
I believe the answer is:
lawyer
'solicitor' is the definition.
(I know that solicitor can be written as lawyer)
This is the entire clue.
(Other definitions for lawyer that I've seen before include ""Let's kill all the --s" (Henry VI/2)" , "Legal practitioner" , "Member of the legal profession" , "Solicotor or barrister" , "Man at the bar?" .)
