Cunning statue design (6)
I believe the answer is:
astute
'cunning' is the definition.
(I've seen this in another clue)
'statue design' is the wordplay.
'design' indicates an anagram.
'statue' is an anagram of 'ASTUTE'.
(Other definitions for astute that I've seen before include "Clever and crafty" , "Nymph who was transformed into a laurel tree to escape Apollo" , "Sharp-witted" , "smart (with some self-interest?)" , "Peerceptive" .)
