Imitate Church with child-friendly summary (6)
I believe the answer is:
apercu
'summary' is the definition.
(apercu is a kind of summary)
'imitate church with child-friendly' is the wordplay.
'imitate' becomes 'ape' (synonyms).
'church' becomes 'RC' (abbreviation for Roman Catholic).
'with' is a charade indicator (letters next to each other).
'child-friendly' becomes 'u' (I am not sure about this - if you are sure you should believe this answer much more).
'ape'+'rc'+'u'='APERCU'
Can you help me to learn more?
(Other definitions for apercu that I've seen before include "Precis, brief outline" , "Glimpse" , "Brief sketch, outline" , "summary, insight; race up (anag.)" , "Short synopsis, precis" .)
