Given church land, bishop bursts into song (5)
I believe the answer is:
glebe
'given church land' is the definition.
'glebe' can be an answer for 'land' (glebe is a kind of land). I am not sure about the 'given church' bit.
'bishop bursts into song' is the wordplay.
'bishop bursts' becomes 'b' (I am not sure about this - if you are sure you should believe this answer much more).
'into' indicates putting letters inside.
'song' becomes 'glee' (I've seen this before).
'b' inserted into 'glee' is 'GLEBE'.
Can you help me to learn more?
(Other definitions for glebe that I've seen before include "clerical plot" , "Church property" , "Land owned by parish" , "Piece of church-owned land" , "church territory" .)
