Striped big cat (5)
I believe the answer is:
tiger
'striped big cat' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tiger that I've seen before include "Dead Celtic feline" , "Beast as Shere Khan" , "One of the big cats" , "audacious person" , "''... ... burning bright, in the forests of the night'' (Blake)" .)
