This endlessly contributes to finance for Scottish region (7)
I believe the answer is:
lothian
'scottish region' is the definition.
(I've seen this before)
'this endlessly contributes to finance' is the wordplay.
'endlessly' means to remove the last letter.
'contributes to' indicates putting letters inside.
'finance' becomes 'loan' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'this' with its last letter taken off is 'thi'.
'thi' put inside 'loan' is 'LOTHIAN'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for lothian that I've seen before include "Historic Scottish region" , "Edinburgh area" .)
