One of those in church report, for example, going around with Mr Hyde, for instance
I believe the answer is:
alter ego
'one of those in church report for example going' is the definition.
I can't judge whether this defines the answer.
'around with mr hyde for instance' is the wordplay.
'around' becomes 'o' (I've seen this in other clues).
'with' says to put letters next to each other.
'mr hyde' becomes 'alter' (I can't explain this - if you can you should give a lot more credence to this answer).
'for instance' becomes 'eg' ('e.g.' can be a synonym of 'for instance').
'alter'+'eg'='altereg'
'o' after 'altereg' is 'ALTER EGO'.
Can you help me to learn more?
(Other definitions for alter ego that I've seen before include "Mister Hyde, for example" , "One's secondary personality" , "Is it Kent" , "A second personality or intimate friend" , "'One's alternative personality (5,3)'" .)
