Lawyer's sign (7)
I believe the answer is:
shingle
'lawyer's sign' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shingle that I've seen before include "A mass of seashore pebbles" , "Loose stones" , "Here one comes close to the main" , "Water-worn pebbles - roofing tile" , "may be lying on the beach" .)
