Anger about whatever Eve lost (5)
I believe the answer is:
wrath
'anger' is the definition.
(I know that wrath is a type of rage)
'about whatever eve lost' is the wordplay.
'about' is an anagram indicator.
'lost' suggests deleting specific letters.
'whatever' with 'eve' removed is 'whatr'.
'whatr' anagrammed gives 'WRATH'.
(Other definitions for wrath that I've seen before include "Fury" , "head in Scotland" , "Angry indignation" , "Extreme anger" , "Failure to keep cool" .)
