Land in single benefice (5)
I believe the answer is:
glebe
'land' is the definition.
(I know that glebe is a type of land)
'in single benefice' is the wordplay.
'in' says the answer is hidden in the clue.
'GLEBE' is hidden within 'single benefice'.
(Other definitions for glebe that I've seen before include "Land owned by parish" , "soil" , "land of the living?" , "clerical plot" , "Church property" .)
