Roaring cat (4)
I believe the answer is:
lion
'roaring cat' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lion that I've seen before include "Sought after celebrity (showing great strength and courage?)" , "Important figure" , "Touring rugby player" , "Big cat with pride" , "Courageous person" .)
