Close to tears after holiday snaps (6)
I believe the answer is:
breaks
'snaps' is the definition.
(I've seen this before)
'close to tears after holiday' is the wordplay.
'close to' says to take the final letters (the close/ending of).
'after' is a charade indicator (letters next to each other).
'holiday' becomes 'break' (I've seen this before).
The final letter of 'tears' is 's'.
's' put after 'break' is 'BREAKS'.
(Other definitions for breaks that I've seen before include "Intervals" , "Knocks into pieces" , "Interruptions of continuity" , "Ruptures" , "Fractures or splits" .)
