After refreshment, writing sides (5)
I believe the answer is:
teams
'sides' is the definition.
'after refreshment writing' is the wordplay.
'after' means one lot of letters go next to another.
'refreshment' becomes 'tea' (I've seen this before).
'writing' becomes 'ms' (abbreviation for manuscript).
'tea' next to 'ms' is 'TEAMS'.
(Other definitions for teams that I've seen before include "Groups or troupes" , "Groups of people working together" , "Crews" , "Sports sides" , "Squads" .)
