Visitor at bingo? (6)
I believe the answer is:
caller
This clue could be a double definition.
'visitor' is the first definition.
(caller is a kind of visitor)
'bingo?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'at' is the link.
Can you help me to learn more?
(Other definitions for caller that I've seen before include "Visitor" , "Someone phoning" , "One visits" , "One paying a brief visit" , "Person on the line" .)
