Sin that precedes the fall? (5)

I believe the answer is:

pride

I'm a little stuck... Click here to teach me more about this clue!

'sin' is the definition.
(pride is a kind of sin)

I can't explain the rest of the clue.

(Other definitions for pride that I've seen before include "Deadly sin (of lions?)" , "Leonine family" , "group of animals" , "Excessive self-esteem" , "Group of lions" .)

I've seen this clue in The Times.
