It's cold in the forest for the bucks in America (4)
I believe the answer is:
cash
'the forest for the bucks in america' is the definition.
I can't judge whether this defines the answer.
'it's cold in' is the wordplay.
'it's cold' becomes 'c' (eg on taps).
'in' becomes 'ash' (I can't explain this - if you can you should give a lot more credence to this answer).
'c'+'ash'='CASH'
Can you help me to learn more?
(Other definitions for cash that I've seen before include ""Readies"" , "Spondulicks" , "Hard currency" , "Funds" , "bread" .)
