La Paz (anag.) (5)
I believe the answer is:
'la paz anag' is the definition.
I can't tell whether this definition defines the answer.
'la paz anag' is the wordplay.
'anag' is an anagram indicator.
'lapaz' with letters rearranged gives 'PLAZA'.
Can you help me to learn more?
(Other definitions for plaza that I've seen before include "Shopping mall", "Open urban square or public area", "Hotel", "Public square, in Italy", "Sp. square, market-place".)
