Admitted having been bought, perhaps (5)
I believe the answer is:
owned
'admitted' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for owned that I've seen before include "Possessed; admitted" , "admitted making confession" , "to oneself?" , "made a confession" , "Confessed" .)
