Integrated student drinking beers at clubs (9)
I believe the answer is:
coalesced
'integrated' is the definition.
'student drinking beers at clubs' is the wordplay.
'student' becomes 'coed' (co-ed is a kind of student).
'drinking' is an insertion indicator.
'beers' becomes 'ales' (I've seen this before).
'at' is a charade indicator (letters next to each other).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'ales'+'c'='alesc'
'coed' enclosing 'alesc' is 'COALESCED'.
(Other definitions for coalesced that I've seen before include "Came together as one" , "Mixed" .)
