Merchant or businessman (6)

I believe the answer is:

trader

I believe this clue is a double definition.

'merchant' is the first definition.
(I know that Trader is a type of merchant)

'businessman' is the second definition.
(I know that Trader is a type of trader)

(Other definitions for trader that I've seen before include "Retard (anag.)" , "One in business" , "Dealer, monger" , "One buys and sells" , "Tarred like merchant" .)

I've seen this clue in the Sydney Morning Herald.
