Demand a visit (4)
I believe the answer is:
call
This clue is a double definition.
'demand' is the first definition.
(call is a kind of demand)
'a visit' is the second definition.
(call is a kind of visit)
(Other definitions for call that I've seen before include "Summon - visit" , "Phone - demand" , "Assign a name to" , "Shout - name" , "Cry - summon" .)
