Right or privilege (11)
I believe the answer is:
prerogative
I believe this clue is a double definition.
'right' is the first definition.
(I know that prerogative is a type of right)
'privilege' is the second definition.
(I know that privilege can be written as prerogative)
(Other definitions for prerogative that I've seen before include "Exclusive right/privilege" , "Right, privilege" .)
