English admiral (6)
I believe the answer is:
nelson
'english admiral' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for nelson that I've seen before include "Sea-lord who loved Lady Hamilton" , "English admiral, mortally wounded at Trafalgar" , "Admiral on a column" , "Naval hero, d. 21 October 1805" , "'Horatio ..., English admiral (6)'" .)
