Partner finally raised a pound for support (8)
I believe the answer is:
espousal
'support' is the definition.
(I know that espousal is a type of approval)
'partner finally raised a pound' is the wordplay.
I cannot quite see how this works, but
'partner' could be 's' and 's' is found in the answer.
'a' is present in the answer.
'pound' could be 'l' (the pound sign is based on an L) and 'l' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for espousal that I've seen before include "Backing, support" , "Adoption (of a cause) - USA's pole (anag)" , "Acceptance with approval" , "championship" , "Favourable reception" .)
