Splendid — tearing (7)
I believe the answer is:
ripping
This clue is a double definition.
'splendid' is the first definition.
(I know that splendid can be written as ripping)
'tearing' is the second definition.
(ripping is a kind of tearing)
(Other definitions for ripping that I've seen before include "Knockout" , "Tearing forcefully" , "Excellent; tearing" , "producing tears?" , "Tearing - splendid!" .)
