Drink for each meal (6)
I believe the answer is:
supper
'meal' is the definition.
(I know that Supper is a type of meal)
'drink for each' is the wordplay.
'drink' becomes 'sup' (to sup is to drink).
'for each' becomes 'per' (I've seen this before).
'sup'+'per'='SUPPER'
(Other definitions for supper that I've seen before include "has one had a few drinks?" , "Eats late" , "Early evening meal" , "Evening repast" , "Light evening meal" .)
