See a game at the weekend (4)
I believe the answer is:
look
'see' is the definition.
(I know that see can be written as look)
'a game at the weekend' is the wordplay.
'a game' becomes 'loo' (historic card game found in Jane Austen novels).
'at' says to put letters next to each other.
'the weekend' becomes 'k' (I've seen this in other clues).
'loo'+'k'='LOOK'
(Other definitions for look that I've seen before include "Direct the eye to" , "Seem" , "See - air" , "Get an eyeful" , "See; appearance" .)
