A lot of money put on one number here? (6)
I believe the answer is:
casino
'a lot' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'money put on one number here?' is the wordplay.
'money' becomes 'c'.
'put on' says to put letters next to each other.
'one number' becomes 'no' (abbreviation for 'number').
'here?' becomes 'asi' (I can't justify this - if you can you should give a lot more credence to this answer).
'no' put after 'asi' is 'asino'.
'c'+'asino'='CASINO'
'of' is the link.
Can you help me to learn more?
(Other definitions for casino that I've seen before include "--- Royale (Fleming)" , "Gambling establishment" , "Imitate" , "Gaming establishment" , "Gaming house" .)
