Lion seen in the jungle occasionally (3)
I believe the answer is:
leo
'lion' is the definition.
('lion' in Latin)
'in the jungle occasionally' is the wordplay.
'in' says the answer is hidden in the clue.
'LEO' is hidden within 'jungle occasionally'.
'seen' acts as a link.
(Other definitions for leo that I've seen before include "house" , "one of several popes" , "Lion sign of the Zodiac" , "Man" , "certain stars" .)
