Capital charge? (8)
I believe the answer is:
interest
This clue might be a double definition.
'capital' is the first definition.
The definition and answer can be both related to property as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'charge?' is the second definition.
(interest is a kind of charge)
Can you help me to learn more?
(Other definitions for interest that I've seen before include "Benefit" , "Payment on deposit account" , "Condition of curiosity about amount paid for use of money" , "Share - concern" , "Care" .)
