Church employee right on the edge (6)
I believe the answer is:
verger
'church' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'employee right on the edge' is the wordplay.
'employee right' becomes 'r' (I am not sure about this - if you are sure you should believe this answer much more).
'on' means one lot of letters go next to another.
'the edge' becomes 'verge' (verge is a kind of edge).
'r' put after 'verge' is 'VERGER'.
Can you help me to learn more?
(Other definitions for verger that I've seen before include "Church officer" , "Church caretaker and attendant" , "Church official" .)
