Western source of wealth? (7)
I believe the answer is:
bonanza
This clue might be a double definition.
'western source' is the first definition.
'bonanza' can be an answer for 'source' (I have seen 'Source of wealth' mean 'bonanza' so perhaps 'source' could also mean 'bonanza'). I am unsure of the 'western' bit.
'wealth?' is the second definition.
(I've seen this before)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bonanza that I've seen before include "Event creating a sudden increase in wealth" , "Unexpected rich windfall" , "Source of wealth or good fortune" , "Source of good luck or wealth" , "Source of great and sudden wealth" .)
