Leo's hauteur? (5)
I believe the answer is:
pride
This clue might be a double definition.
'leo's' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'hauteur?' is the second definition.

Can you help me to learn more?
(Other definitions for pride that I've seen before include "Company of lions" , "Dignity" , "group of animals" , "big cats" , "Vanity" .)
