Cut in a game of cards (7)
I believe the answer is:
abridge
'cut' is the definition.
('abridge' can be a synonym of 'cut')
'a game of cards' is the wordplay.
'game of cards' becomes 'bridge' (I've seen this before).
'a'+'bridge'='ABRIDGE'
'in' is the link.
(Other definitions for abridge that I've seen before include "Concentrate" , "(US) cattle-pen" , "Make shorter in brigade" , "Shorten, a book say, without losing the sense" , "Edit down" .)
