Give rage in order to afflict (8)
I believe the answer is:
aggrieve
'afflict' is the definition.
(aggrieving is a kind of afflicting)
'give rage in order' is the wordplay.
'in order' indicates an anagram (the letters in a new order).
'give'+'rage'='giverage'
'giverage' with letters rearranged gives 'AGGRIEVE'.
'to' acts as a link.
(Other definitions for aggrieve that I've seen before include "Pain or injure" , "Cause pain to; distress" , "Break the heart" , "Ill-use" , "Cause annoyance to" .)
