Mopes about at meeting (5)
I believe the answer is:
epsom
'meeting' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I can't see?
'mopes about' is the wordplay.
'about' indicates an anagram.
'mopes' anagrammed gives 'EPSOM'.
'at' is the link.
Can you help me to learn more?
(Other definitions for epsom that I've seen before include "Classic racecourse" , "Home to the Derby and the Oakes" , "Town with racecourse" , "& 5 Purgative medicine" , "The Oaks and Derby are run here" .)
