One who judges fools accordingly, right? (8)
I believe the answer is:
assessor
'one who judges' is the definition.
(I've seen this before)
'fools accordingly right?' is the wordplay.
'fools' becomes 'asses' (ass is a kind of fool).
'accordingly' becomes 'so' (synonyms).
'right?' becomes 'r' (common abbreviation).
'asses'+'so'+'r'='ASSESSOR'
(Other definitions for assessor that I've seen before include "Legal adviser" , "property valuer" , "Evaluator, estimator" , "One estimates the value of property" , "Official to evaluate property" .)
