Show English church accepting French wine (6)
I believe the answer is:
evince
'show' is the definition.
('evince' can be a synonym of 'show')
'english church accepting french wine' is the wordplay.
'english' becomes 'e' (abbreviation).
'church' becomes 'ce' (abbreviation for Church of England).
'accepting' indicates putting letters inside.
'french wine' becomes 'vin' (I've seen this before).
'e'+'ce'='ece'
'ece' placed around 'vin' is 'EVINCE'.
(Other definitions for evince that I've seen before include "Make evident" , "Prove beyond doubt" , "Indicate (something)" , "Indicate or display, say a feeling" , "Show or display clearly" .)
