Profits coming in happily on anniversary? (7)
I believe the answer is:
returns
'profits coming in happily on anniversary?' is the definition.
'returns' can be an answer for 'profits' (I've seen this before). I am unsure of the 'coming in happily on anniversary?' bit.
'on anniversary?' is the wordplay.
'on' becomes 're' (regarding).
'anniversary?' becomes 'turns' (I can't explain this - if you can you should give a lot more credence to this answer).
're'+'turns'='RETURNS'
Can you help me to learn more?
(Other definitions for returns that I've seen before include "Goes or comes back" , "Goods sent back" , "Hands back" , "Brings or comes back" , "Profits" .)
