Fired with anger (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ire
'anger' is the definition.
(ire is intense rage)
'fired with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'IRE' can be found hidden inside 'fired'.
(Other definitions for ire that I've seen before include "Strong emotion" , "Fury" , "Displeasure" , "Intense anger" , "Irritation, anger" .)
