Side given drink for morale? (4,6)
I believe the answer is:
team spirit
'morale?' is the definition.
('team spirit' can be a synonym of 'morale')
'side given drink' is the wordplay.
'side' becomes 'team' (a side is a sporting team).
'given' is a charade indicator (letters next to each other).
'drink' becomes 'spirit' (I've seen this before).
'team'+'spirit'='TEAM SPIRIT'
'for' is the link.
(Other definitions for team spirit that I've seen before include "displaying camaraderie" , "staff bonus?" , "Esprit de corps" , "feeling of camaraderie" , "Cooperative had plenty of?" .)
