A spell of cold weather and a card game (4)
I believe the answer is:
snap
'a spell of cold weather and a card game' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for snap that I've seen before include "Photograph - card game" , "Simple card game - gotcha!" , "Click! - a photograph!" , "Pans out in simple card game" , "that's a copy!" .)
