Sounds like one paying for farm accommodation (4)
I believe the answer is:
byre
'accommodation' is the definition.
(I have seen 'neat accommodation' mean 'byre' so perhaps 'accommodation' could also mean 'byre')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for byre that I've seen before include "Durham's cover" , "Where stock is kept" , "Cow shelter" , "farm building" , "Cow shed" .)
