Be, live (5)
I believe the answer is:
exist
I believe this is a double definition.
'be' is the first definition.
(I know that be can be written as exist)
'live' is the second definition.
(I know that live can be written as exist)
(Other definitions for exist that I've seen before include "Survive" , "Live" , "Have objective reality" , "Be alive" , "Subsist" .)
