Perhaps select pictures for office in religious establishment (6)
I believe the answer is:
curate
This clue might be a double definition.
'perhaps select pictures for' is the first definition.
The definition suggests a singular noun which matches the answer.
'office in religious establishment' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
Can you help me to learn more?
(Other definitions for curate that I've seen before include "Organize a museum or exhibition" , "Churchman" , "A truce (anag)" , "Assistant cleric" , "assistant barman in Ireland" .)
