I believe the answer is:
deceitful
'is misleading' is the definition.
(synonyms)
'deft clue i recast' is the wordplay.
'recast' indicates an anagram.
'deft'+'clue'+'i'='deftcluei'
'deftcluei' with letters rearranged gives 'DECEITFUL'.
(Other definitions for deceitful that I've seen before include "cheating" , "Sly" , "unreliable" , "Untruthful" , "Dishonest" .)
