The necessary ins and outs? (4,4)
I believe the answer is:
cash flow
This might be a double definition.
'the necessary' is the first definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'ins and outs?' is the second definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for cash flow that I've seen before include "business's finances" , "Movement of money" , "liquidity issue?" , "A must for solvent businesses" , "Movement of rhino" .)
