Medic to lie about being compliant (6)
I believe the answer is:
docile
'compliant' is the definition.
(thesaurus)
'medic to lie about' is the wordplay.
'medic' becomes 'doc' (I've seen this before).
'about' is an anagram indicator.
'lie' anagrammed gives 'ile'.
'doc'+'ile'='DOCILE'
'being' is the link.
(Other definitions for docile that I've seen before include "Gentle and teachable" , "Willing to be taught or led" , "Quiet, willing to obey" , "Easily managed and trainable" , "Tractable and pliant" .)
