Current rent (3)
I believe the answer is:
rip
'rent' is the definition.
(rent can mean a tear in something)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rip that I've seen before include "Letters for the deceased" , "Letters often seen on gravestones" , "comment on one passing" , "dissolute character" , "Rest in peace" .)
