Where the citizens suffered a bellyful? (4)
I believe the answer is:
troy
'where the citizens suffered a bellyful?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for troy that I've seen before include "City besieged by the Greeks - system of gem weight measurement" , "Legendary ancient city of northwest Anatolia" , "System of weights; ancient city in Turkey" , "Ancient city besieged to free beautiful Helen" , "Where beautiful Helen came from" .)
