Charged the one who puts up some defence (7)
I believe the answer is:
accused
'charged' is the definition.
('accuse' can be a synonym of 'charge')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for accused that I've seen before include "Levelled a charge against" , "Person being charged" , "Indicted" , "He who stands in the dock" , "Defendant appearing on a criminal charge" .)
