Counsel gives notice to a gripper (6)
I believe the answer is:
advice
'counsel' is the definition.
(I've seen this before)
'notice to a gripper' is the wordplay.
'notice' becomes 'ad' (short for advert).
'to a gripper' becomes 'vice' (I have seen 'Strong gripper' mean 'vice' so perhaps 'gripper' could also mean 'vice').
'ad'+'vice'='ADVICE'
'gives' acts as a link.
(Other definitions for advice that I've seen before include "Opinion offered as to future action" , "tip" , "Counselling" , "Counsel given" , "Guidance; delivery note" .)
