Stop living in disobedience (3)
I believe the answer is:
die
'stop living' is the definition.
(I've seen this before)
'in disobedience' is the wordplay.
'in' says the answer is hidden in the clue.
'DIE' is hidden within 'disobedience'.
(Other definitions for die that I've seen before include "THIRD PART OF 24" , "Engraved device that stamps design on coins" , "Expire" , "Pass from physical life" , "A device used for casting metal" .)
