A lawyer's leg man? (5)
I believe the answer is:
legal
'a lawyer's leg man?' is the definition.
I can't tell whether this definition defines the answer.
'leg man?' is the wordplay.
'man?' becomes 'Al'.
'leg'+'al'='LEGAL'
Can you help me to learn more?
(Other definitions for legal that I've seen before include "associated with silk business?" , "Above board" , "It's acceptable" , "Authorized" , "Street - (1978 Dylan album)" .)
