Pulls to pieces for crying (5)
I believe the answer is:
tears
This clue is a double definition.
'pulls to pieces' is the first definition.
(I've seen this in another clue)
'crying' is the second definition.
(I know that crying can be written as tears)
'for' acts as a link.
(Other definitions for tears that I've seen before include "damaging to paper" , "See 1" , "See 12" , "Rush special" , "Water in eyes" .)
