Lawyer puzzled on clues (7)
I believe the answer is:
counsel
'lawyer' is the definition.
(counsel is a kind of lawyer)
'puzzled on clues' is the wordplay.
'puzzled' indicates anagramming the letters.
'on'+'clues'='onclues'
'onclues' is an anagram of 'COUNSEL'.
(Other definitions for counsel that I've seen before include "Advocate" , "Advice; barrister" , "Legal adviser" , "In court brief" , "kept by the uncommunicative" .)
