Commission made gains and raked in the dollars (6)
I believe the answer is:
assign
'commission' is the definition.
(I've seen this in another clue)
'gains and raked in the dollars' is the wordplay.
I cannot quite understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
'dollars' could be 'ss' (two S's - S resembles the dollar symbol) and 'ss' is located in the answer.
This explanation may well be incorrect...
'made' acts as a link.
Can you help me to learn more?
(Other definitions for assign that I've seen before include "Appoint to a duty" , "Transfer (legal rights)" , "Allocate or transfer" , "Give a task to" , "Attribute" .)
