African lion disturbed an American (11)
I believe the answer is:
californian
'an american' is the definition.
(Californian is an example)
'african lion disturbed' is the wordplay.
'disturbed' indicates anagramming the letters (the order of letters is disturbed).
'african'+'lion'='africanlion'
'africanlion' anagrammed gives 'CALIFORNIAN'.
(Other definitions for californian that I've seen before include "Western state" , "from part of America" , "Of an American state" , "like Zinfandel?" .)
