A factor in becoming more impoverished (6)
I believe the answer is:
broker
'a factor' is the definition.
(I know that factor can be written as broker)
'becoming more impoverished' is the wordplay.
I cannot quite understand how this works, but
'impoverished' could be 'broke' (breaking is a kind of impoverishing) and 'broke' is found within the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for broker that I've seen before include "Negotiate with" , "A dealer in stocks and shares" , "One buys and sells for others" , "Middleman, dealer" , "See 7" .)
