Grounds to accept this setter's judgement (8)
I believe the answer is:
estimate
'judgement' is the definition.
(I know that estimate is a type of judgement)
'grounds to accept this setter's' is the wordplay.
I cannot really understand how this works, but
'setter's' could be 'im' (referring to the crossword setter) and 'im' is located in the answer.
'grounds' could be 'estate' (I've seen this before) and 'estate' is located in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for estimate that I've seen before include "Guess the cost" , "Judge the approximate value" , "Reckon value" , "Meatiest (anag) - figure" , "Rough cost" .)
