Illicit liquor from house overlooking old church (5)
I believe the answer is:
hooch
'illicit liquor' is the definition.
(I've seen this before)
'house overlooking old church' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'overlooking' means one lot of letters go next to another (down clues only).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'church' becomes 'ch' (common abbreviation).
'ho'+'o'+'ch'='HOOCH'
'from' is the link.
(Other definitions for hooch that I've seen before include "Illicit alcohol" , "Strong illicit liquor" , "Illicitly distilled spirit" , "alcoholic drink" , "moonshine" .)
