Study after tabloid backed plot (6)
I believe the answer is:
garden
'plot' is the definition.
(I know that garden is a type of plot)
'study after tabloid backed' is the wordplay.
'study' becomes 'den' (term for a study or office).
'after' means one lot of letters go next to another.
'tabloid' becomes 'rag' (informal term for a tabloid newspaper).
'backed' is a reversal indicator.
'rag' backwards is 'gar'.
'den' put after 'gar' is 'GARDEN'.
(Other definitions for garden that I've seen before include "Domestic growing area" , "House with extensive grounds" , "Cultivated area" , "Flower-plot" , "Place to grow plants" .)
