Somewhat loves selling ship (6)
I believe the answer is:
Here is my best explanation:
'ship' is the definition.
(I've seen this before)
'somewhat loves selling' is the subsidiary indication.
'somewhat' indicates the answer is hidden within the clue.
'vessel' is hidden within 'loves selling'.
(Other definitions for vessel that I've seen before include "A ship or kitchen utensil", "A ship, a cup", "Liquid container", "Artery or ship?", "Watercraft or water container", "Container - ship", "bowl?", "Receptacle - ship", "Kind of ship or a kitchen pot (6)" and "Container - boat".)
