Made a rip in (4)
I believe the answer is:
tore
'made a rip in' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tore that I've seen before include "'Ripped, rent (4)'" , "Ripped; went fast" , "Rote (anag.)" , "Pulled something apart forcefully" , "Ripped something apart" .)
