Handle call (4)
I believe the answer is:
name
I believe this is a double definition.
'handle' is the first definition.
(handle can mean a name or nickname)
'call' is the second definition.

(Other definitions for name that I've seen before include "By which one is known" , "Specify; famous person" , "Mean sort of appellation" , "Handle" , "Call; reputation" .)
