Cleric had arranged minor supervision (9)
I believe the answer is:
childcare
'minor supervision' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'cleric had arranged' is the wordplay.
'arranged' indicates an anagram.
'cleric'+'had'='clerichad'
'clerichad' with letters rearranged gives 'CHILDCARE'.
Can you help me to learn more?
(Other definitions for childcare that I've seen before include "protection of the young" , "Responsibility for family" , "concern for charges" , "Youth work" .)
