Tact and art redesigned as lure (7)
I believe the answer is:
attract
'lure' is the definition.
(thesaurus)
'tact and art redesigned' is the wordplay.
'and' means one lot of letters go next to another (I've seen this in other clues).
'redesigned' indicates an anagram.
'tact' put after 'art' is 'arttact'.
'arttact' anagrammed gives 'ATTRACT'.
'as' is the link.
(Other definitions for attract that I've seen before include "Act as a magnet" , "Entice" , "Bring in" , "Lure" , "Behave like a magnet" .)
