Mopes about at meeting (5)
I believe the answer is:
epsom
'meeting' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?
'mopes about' is the wordplay.
'about' is an anagram indicator.
'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" .)
