Where Plato met commander gathering troops? (5)
I believe the answer is:
agora
'where plato met' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'commander gathering troops?' is the wordplay.
'commander' becomes 'aga' (historical term for a Muslim military commander).
'gathering' is an insertion indicator (gather can mean to acquire or bring in).
'troops?' becomes 'or' (military abbreviation for other ranks).
'aga' placed around 'or' is 'AGORA'.
Can you help me to learn more?
(Other definitions for agora that I've seen before include "Assembly or market place in ancient Greece" , "Place to gather" , "A public place" , "meeting place" , "market in Athens" .)
