Look curiously around storage unit at residence, one for clergy (10)
I believe the answer is:
presbytery
'one for clergy' is the definition.
(thesaurus)
'look curiously around storage unit at residence' is the wordplay.
'look curiously' becomes 'pry' (to pry is to be nosy or curious).
'around' means one lot of letters goes inside another.
'storage unit' becomes 'byte' (computer storage).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'residence' becomes 'res'.
'byte' put after 'res' is 'resbyte'.
'pry' placed around 'resbyte' is 'PRESBYTERY'.
(Other definitions for presbytery that I've seen before include "Sanctuary" , "Clergy house" .)
