A winter break? (4)
I believe the answer is:
snap
I believe this clue is a double definition.
'a winter' is the first definition.
(thesaurus)
'break?' is the second definition.
(I know that snap is a type of break)
(Other definitions for snap that I've seen before include "Collapse" , "Photograph - card game" , "Cut" , "unexpected? > Same here!" , "Ginger biscuit" .)
