Told to re-do, goes berserk, getting angry (7)
I believe the answer is:
ordered
'told' is the definition.
('order' can be a synonym of 'tell')
're-do goes berserk getting angry' is the wordplay.
'goes berserk' is an anagram indicator.
'getting' means one lot of letters go next to another.
'angry' becomes 'red' (I've seen this in other clues**).
're'+'do'='redo'
'redo' with letters rearranged gives 'orde'.
'orde'+'red'='ORDERED'
'to' is the link.
(Other definitions for ordered that I've seen before include "requested" , "Charged; tidy" , "Regulated" , "Gave instruction, commanded" , "Issued commands" .)
