Has ability in buccaneering (3)
I believe the answer is:
can
'has ability' is the definition.
(I've seen this in another clue)
'in buccaneering' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CAN' is hidden within 'buccaneering'.
(Other definitions for can that I've seen before include "let go in the US" , "May" , "Possesses ability" , "has power" , "Metallic container" .)
