Sharp statue design (6)
I believe the answer is:
astute
'sharp' is the definition.
(I've seen this before)
'statue design' is the wordplay.
'design' indicates anagramming the letters.
'statue' is an anagram of 'ASTUTE'.
(Other definitions for astute that I've seen before include "Wise" , "Shrewd and clever" , "Sharp-witted" , "intelligent" , "Subtle" .)
