Wee drink ahead of a play (5)
I believe the answer is:
Here is my best explanation:
'play' is the definition.
('drama' can be a synonym of 'play')
'wee drink ahead of a' is the wordplay.
'wee drink' becomes 'dram' (I've seen this before).
'ahead of' says to put letters next to each other (I've seen this in other clues).
(Other definitions for drama that I've seen before include "Emotional sequence of events (made out of a crisis?)", "Play (as a genre)", "Hamlet, say", "sensation", "spectacle of emotion", "Highly emotional episode", "Play for theatre", "Show", "Emotional episode" and "Histrionics?".)
