Seething state (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ire
'seething state' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ire that I've seen before include "Anger, rage" , "Outrage" , "resentment" , "Strong emotion" , "passionate feeling" .)
