Tiger seen moving? Not here, where lions are! (9)
I believe the answer is:
serengeti
'not here where lions are' is the definition.
I know nothing about this answer so I can't judge whether this works.
'tiger seen moving?' is the wordplay.
'moving?' is an anagram indicator (letters are moved around).
'tiger'+'seen'='tigerseen'
'tigerseen' anagrammed gives 'SERENGETI'.
Can you help me to learn more?
(Other definitions for serengeti that I've seen before include "Wildlife preserve (and National Park) in Tanzania" , "Vast plain" , "area of the plain" , "where lion holds sway?" , "area of Tanzania" .)
