Payment received by letter? (6)
I believe the answer is:
rental
This clue could be a double definition.
'payment' is the first definition.
(I've seen this before)
'received by letter?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for rental that I've seen before include "Something paid for hire" , "Learnt (anag) -- lease" , "Payment to landlord" , "Tenant's payment" , "Money paid for hire" .)
