Spooner’s mentioned harsh accommodation (9)
I believe the answer is:
bedsitter
'accommodation' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bedsitter that I've seen before include "One-roomed accommodation" , "pad" , "Digs" , "Modest accommodation" .)
