Recalled substance of visit (4)
I believe the answer is:
call
'visit' is the definition.
(call is a kind of visit)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for call that I've seen before include "Visit; shout" , "Visit; cry out" , "Telephone - give a name" , "Cry - summon" , "Ring or visit" .)
