Rector joins fellow in church for food and drink (5)
I believe the answer is:
cheer
'food and drink' is the definition.
(I've seen this before)
'rector joins fellow in church' is the wordplay.
'rector' becomes 'r'.
'joins' says to put letters next to each other.
'fellow' becomes 'he' (I've seen this in other clues**).
'in' means one lot of letters goes inside another.
'church' becomes 'ce' (abbreviation for Church of England).
'he' inserted within 'ce' is 'chee'.
'r' after 'chee' is 'CHEER'.
'for' acts as a link.
(Other definitions for cheer that I've seen before include "Applaud; mood" , "Urge on" , "Lift the mood" , "Inspirit" , "party refreshment?" .)
