Range generates fury (5)
I believe the answer is:
anger
'fury' is the definition.
(fury is intense anger)
'range generates' is the wordplay.
'generates' is an anagram indicator.
'range' with letters rearranged gives 'ANGER'.
(Other definitions for anger that I've seen before include "Provoke annoyance" , "One of the seven deadly sins" , "Strongly annoy" , "Strong displeasure" , "Wrath, ire" .)
