Scope of uncontrolled anger (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
range
'scope' is the definition.
('range' can be a synonym of 'scope')
'uncontrolled anger' is the wordplay.
'uncontrolled' indicates anagramming the letters.
'anger' is an anagram of 'RANGE'.
'of' is the link.
(Other definitions for range that I've seen before include "Open grazing land or cooking stove" , "Extent - cooker" , "Compass - scope" , "Vocal compass" , "Scope - cowboys' home" .)
