New range of emotion (5)
I believe the answer is:
anger
'emotion' is the definition.
(anger is a kind of emotion)
'new range' is the wordplay.
'new' is an anagram indicator.
'range' is an anagram of 'ANGER'.
'of' acts as a link.
(Other definitions for anger that I've seen before include "Feeling of vexation" , "There's fury" , "Nettle" , "Incense" , "Annoyance, displeasure" .)
