Give up work, releasing son to hold sway (5)
I believe the answer is:
reign
'hold sway' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for reign that I've seen before include "Control" , "are unbeatable!" , "Occupy the throne" , "Monarch's rule" , "period in power" .)
