Victorious naval officer in hold (6)
I believe the answer is:
nelson
'hold' is the definition.
(wrestling hold)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nelson that I've seen before include "Horatio - - , naval commander" , "Admiral on a column" , "English naval commander - wrestling hold" , "Admiral (who had the touch)" , "Lady Hamilton's navy lover" .)
