Let loose panther on monument in Greece (9)
I believe the answer is:
parthenon
'monument in greece' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'let loose panther on' is the wordplay.
'let loose' indicates an anagram.
'panther' is an anagram of 'parthen'.
'parthen'+'on'='PARTHENON'
Can you help me to learn more?
(Other definitions for parthenon that I've seen before include "ruined Greek temple" , "Temple on the Athenian Acropolis" , "Temple of Athene on Acropolis in Athens" , "Ancient temple" , "Tourist attraction of Athens" .)
