Satisfaction of lions (5)
I believe the answer is:
pride
This clue is a double definition.
'satisfaction' is the first definition.
(I know that pride is a type of satisfaction)
'lions' is the second definition.
(pride is the collective noun for a group of lions)
'of' acts as a link.
(Other definitions for pride that I've seen before include "group of animals" , "cause of swelling?" , "Novel by Jane Austen" , "Leonine family" , "Deadly sin (of lions?)" .)
