Land held by single benefice? (5)
I believe the answer is:
glebe
'land' is the definition.
(glebe is a kind of land)
'held by single benefice?' is the wordplay.
'held by' says the answer is hidden in the clue.
'GLEBE' is hidden in the letters of 'single benefice'.
(Other definitions for glebe that I've seen before include "Church property" , "Plot of land belonging to a parish church" , "church territory" , "land of the living?" , "Land owned by parish" .)
