Where the wealthy go on most Mondays (8)
I believe the answer is:
richmond
'where' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'wealthy go on most mondays' is the wordplay.
'wealthy' becomes 'rich' (similar in meaning).
'go' becomes 'ond' (I can't justify this - if you can you should give a lot more credence to this answer).
'on' is a charade indicator (letters next to each other).
'most' means to remove the last letter.
'mondays' becomes 'mm' (an abbreviation for Monday written twice).
'mm' with its last letter taken off is 'm'.
'ond' after 'm' is 'mond'.
'rich'+'mond'='RICHMOND'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for richmond that I've seen before include "Thames-side town" , "Just copes" , "Capital of Virginia, USA" , "Sweet lass of - Hill" , "US state capital" .)
