He profits even when told to sell at a loss (6)
I believe the answer is:
broker
'he profits even' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'told to sell at a loss' is the wordplay.
I cannot really see how this works, but
'told' could be 'broke' (breaking is a kind of telling) 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...
'when' acts as a link.
Can you help me to learn more?
(Other definitions for broker that I've seen before include "He buys and sells for others - say stocks" , "One buys and sells for others" , "intermediary" , "See 7" , "Negotiate with" .)
