A source of food in church outlet (4)
I believe the answer is:
cafe
'outlet' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'a source of food in church' is the wordplay.
'source of' indicates taking the first letters.
'in' indicates putting letters inside.
'church' becomes 'CE' (abbreviation for Church of England).
The first letter of 'food' is 'f'.
'a'+'f'='af'
'af' going within 'ce' is 'CAFE'.
Can you help me to learn more?
(Other definitions for cafe that I've seen before include "A small restaurant of French kind" , "Inexpensive restaurant serving light refreshment" , "Small informal restaurant" , "Small eating place" , "in which one had a meal?" .)
