Regulate fair verdict from ASA? (6)
I believe the answer is:
adjust
'regulate' is the definition.
(to adjust is to regulate or modify)
'fair verdict from asa?' is the wordplay.
I cannot really see how this works, but
'fair' could be 'just' (associated in meaning) and 'just' is found in the answer.
The remaining letters 'ad' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for adjust that I've seen before include "Modify - tweak" , "carry out minor alterations" , "Alter by small amount to make right for use" , "Correct" , "Arrange, put into proper position" .)
