Owner of sword I plant while not going down (7)
I believe the answer is:
samurai
'owner' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for samurai that I've seen before include "Traditional Japanese warrior" , "Sudoku variant" , "Member of military class" , "Historical Japanese warrior" , "Japanese militarist" .)
