Via telephone, flog basic accommodation (4)
I believe the answer is:
cell
'accommodation' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for cell that I've seen before include "Small room for confining a prisoner" , "Basic biological unit" , "Biological unit with a nucleus" , "Animal or plant building unit" , "Lock-up room" .)
