Wrath where inferno not starting (3)
I believe the answer is:
ire
'wrath' is the definition.
(both can mean anger)
'inferno not starting' is the wordplay.
'inferno' becomes 'fire' (I've seen this in another clue).
'not starting' means to remove the first letter.
'fire' with its initial letter taken off is 'IRE'.
'where' is the link.
(Other definitions for ire that I've seen before include "Outrage" , "Hot temper" , "Choler" , "Paddy" , "Irritation, anger" .)
