Not extinct (4)
I believe the answer is:
live
'not extinct' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for live that I've seen before include "Eg, from Kingston" , "Exist in evil" , "Electrically charged" , "Heard or seen as the event takes place and not from a recording" , "Be - unrecorded" .)
