How the minister takes care to stop a badly arranged reunion (10)
I believe the answer is:
pastorally
'how the minister takes care' is the definition.
I can't judge whether this defines the answer.
'stop a badly arranged reunion' is the wordplay.
'badly arranged' indicates an anagram (I've seen this in other clues).
'reunion' becomes 'rally' (I can't explain this - if you can you should believe this answer much more).
'stop'+'a'='stopa'
'stopa' is an anagram of 'pasto'.
'pasto'+'rally'='PASTORALLY'
'to' is the link.
Can you help me to learn more?
(Other definitions for pastorally that I've seen before include "in the countryside" , "as a minister" .)
