Woodland dweller's bank, said to have not much money (7)
I believe the answer is:
roebuck
'woodland dweller's' is the definition.
(type of deer)
'said to have not much money' is the wordplay.
'said' becomes 'roe' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to have' means one lot of letters go next to another.
'not much money' becomes 'buck' (a single dollar).
'roe'+'buck'='ROEBUCK'
'bank' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for roebuck that I've seen before include "Small male deer" , "Being wild" , "Stag" , "reddish-brown jumper" , "does partner" .)
