Aid reduced by church body (7)
I believe the answer is:
chassis
This clue might be a double definition.
'aid reduced by church' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'body' is the second definition.
(I know that chassis is a type of body)
Can you help me to learn more?
(Other definitions for chassis that I've seen before include "Vehicle structure" , "Body frame" , "Car's structural framework" , "vessel's structural framework" , "Body framework" .)
