Edit a clue perhaps to make it clear (9)
I believe the answer is:
elucidate
'make it clear' is the definition.
(thesaurus)
'edit a clue perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'edit'+'a'+'clue'='editaclue'
'editaclue' with letters rearranged gives 'ELUCIDATE'.
'to' is the link.
(Other definitions for elucidate that I've seen before include "Make clear and more comprehensible" , "Throw light on a problem, make clear (9)" , "Make clear, explain" , "Shed light on, clarify" , "Shed light upon" .)
