Turn over paper and study plot (6)
I believe the answer is:
garden
'plot' is the definition.
(garden is a kind of plot)
'turn over paper and study' is the wordplay.
'turn over' says the letters should be written backwards.
'paper' becomes 'rag' (rag is a kind of paper**).
'and' says to put letters next to each other.
'study' becomes 'den' (I've seen this before).
'rag' backwards is 'gar'.
'gar'+'den'='GARDEN'
(Other definitions for garden that I've seen before include "Where, eg, flowers are grown" , "Land round house" , "Area round house" , "Ornamental grounds" , "Green space attached to a house" .)
