Group of lions (5)
I believe the answer is:
pride
'group of lions' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pride that I've seen before include "group of animals" , "Vanity" , "''. . . . . goeth before a fall''" , "Arrogance - self-respect" , "Novel by Jane Austen" .)
