Advocate in Scotland putting railing round street (9)
I believe the answer is:
barrister
'advocate in scotland' is the definition.
'barrister' can be an answer for 'advocate' (a legal advocate). I'm not certain of the 'in scotland' bit.
'railing round street' is the wordplay.
'railing' becomes 'barrier' (railing can mean a bar or barrier).
'round' indicates putting letters inside.
'street' becomes 'st' (abbreviation).
'barrier' going around 'st' is 'BARRISTER'.
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for barrister that I've seen before include "Legal advocate, must be briefed" , "Rarest rib for the eminent lawyer" , "Legal representative" , "A bewigged legal eagle" , "One represents clients in court" .)
