Own or have (7)
I believe the answer is:
possess
I believe this is a double definition.
'own' is the first definition.
(I know that own can be written as possess)
'have' is the second definition.
(I know that have can be written as possess)
(Other definitions for possess that I've seen before include "Have and hold" , "Consume" , "influence" , "Own, keep" , "Have as one's own" .)
