Sense struggle, with son deposing leader (5)
I believe the answer is:
sight
'sense' is the definition.
(sight or vision is a sense)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sight that I've seen before include "Looking" , "something to behold" , "object of especial interest" , "Vista" , "Notice" .)
