Living, not dead (5)
I believe the answer is:
alive
I believe this clue is a double definition.
'living' is the first definition.
(I know that living can be written as alive)
'not dead' is the second definition.
('alive' is the opposite to 'dead')
(Other definitions for alive that I've seen before include "Teeming (with)" , "Vital, vibrant" , "Animated and kicking" , "Active - living" , "Extant" .)
