Sharp statue design (6)
I believe the answer is:
astute
'sharp' is the definition.
(I know that sharp can be written as astute)
'statue design' is the wordplay.
'design' indicates an anagram.
'statue' with letters rearranged gives 'ASTUTE'.
(Other definitions for astute that I've seen before include "Wise" , "Shrewd and clever" , "Sharp-witted" , "intelligent" , "Subtle" .)
