Boozer knocked back wine before neighbourhood meeting (5,5)
I believe the answer is:
local derby
'neighbourhood meeting' is the definition.
'local derby' can be an answer for 'meeting' (I have seen 'Meeting of neighbours' mean 'local derby' so perhaps 'meeting' could also mean 'local derby'). I am unsure of the 'neighbourhood' bit.
'boozer knocked back wine before' is the wordplay.
'boozer' becomes 'local' (I've seen this before).
'knocked back' is a reversal indicator.
'wine' becomes 'red wine' (red is a type of wine).
'before' becomes 'by'.
'red' in reverse letter order is 'der'.
'local'+'der'+'by'='LOCAL DERBY'
Can you help me to learn more?
(Other definitions for local derby that I've seen before include "competition in the neighbourhood" , "Match between nearby teams" , "Nearby game?" , "grudge match?" , "big match" .)
