Payment for ring (4)
I believe the answer is:
toll
This might be a double definition.
'payment' is the first definition.
The answer and definition can be both related to property as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'for ring' is the second definition.
(ring a bell)
Can you help me to learn more?
(Other definitions for toll that I've seen before include "Ring; levy" , "Ring - fee" , "Sum payable to use main road (4)" , "repeated ringing" , "Charge to use bridge/road" .)
