Liberty, say, of an astute disposition (6)
I believe the answer is:
statue
'liberty say' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'an astute disposition' is the wordplay.
'disposition' indicates anagramming the letters.
'astute' with letters rearranged gives 'STATUE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for statue that I've seen before include "Figure, effigy" , "Stone figure" , "Figurine" , "Modelled figure of a human or animal" , "permanent fixture" .)
