Wild West figure, useless in business (6)
I believe the answer is:
cowboy
'wild west figure' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'useless in business' is the wordplay.
I cannot really understand how this works, but
'business' could be 'co' (short for company) and 'co' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cowboy that I've seen before include "Amateurish" , "Wild West character" , "Artisan doing shoddy work" , "Mounted herdsman" , "(Gun-toting?) untrustworthy workman" .)
