Rage of social reformer gripping you, reportedly (4)
I believe the answer is:
fury
'rage' is the definition.
(I know that rage can be written as fury)
'social reformer gripping you reportedly' is the wordplay.
I cannot really see how this works, but
'you' could be 'u' (commonly used in online communication) and 'u' is present in the answer.
'reformer' could be 'fry' (Elizabeth Fry) and 'fry' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for fury that I've seen before include "Great anger or rage" , "Wrath, rage" , "Extreme rage" , "passionate woman" , "'Hell hath no . . . . like a woman scorned" .)
