The charge comes to fifty quid (4)
I believe the answer is:
toll
This clue might be a double definition.
'the charge' is the first definition.
(toll is a kind of charge)
'fifty quid' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'comes to' is the link.
Can you help me to learn more?
(Other definitions for toll that I've seen before include "Form of road tax" , "Payment imposed for the use of a public road" , "number of casualties" , "Charge for using, eg, road" , "Price exacted" .)
