Lurking wild lion and tiger (9)
I believe the answer is:
loitering
'lurking' is the definition.
('loiter' can be a synonym of 'lurk')
'wild lion and tiger' is the wordplay.
'wild' indicates an anagram.
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'lion' put after 'tiger' is 'tigerlion'.
'tigerlion' is an anagram of 'LOITERING'.
(Other definitions for loitering that I've seen before include "Hanging around or lurking" , "Lingering" .)
