Drop and damage (4)
I believe the answer is:
tear
This clue is a double definition.
'drop' is the first definition.
(thesaurus)
'damage' is the second definition.
(thesaurus)
'and' acts as a link.
(Other definitions for tear that I've seen before include "Product of the lachrymal gland" , "speed" , "Rip - eye moisture" , "Drop secreted by the lacrimal glands" , "charge" .)
