Lying to get candy item changed (9)
I believe the answer is:
mendacity
'lying' is the definition.
(thesaurus)
'get candy item changed' is the wordplay.
'get' means one lot of letters go next to another.
'changed' indicates anagramming the letters.
'candy' put next to 'item' is 'candyitem'.
'candyitem' anagrammed gives 'MENDACITY'.
'to' acts as a link.
(Other definitions for mendacity that I've seen before include "Quality or habit of telling lies or being deceitful" , "Lying" , "Untruthfulness" .)
