One expecting payment for warhorse? (7)
I believe the answer is:
charger
This could be a double definition.
'one expecting payment' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'for warhorse?' is the second definition.
(charger is a kind of warhorse)
Can you help me to learn more?
(Other definitions for charger that I've seen before include "One demanding payment" , "A warhorse; a serving-dish" , "Horse - plate" , "Battle horse" , "Horse; flat dish" .)
