Rage, showing passion -- not feminine! (3)
I believe the answer is:
ire
'rage' is the definition.
(I've seen this before)
'passion not feminine' is the wordplay.
'passion' becomes 'fire' (fire is a kind of passion).
'not' indicates named letters should be taken away.
'feminine' becomes 'f' (abbreviation listed in Chambers).
'fire' with 'f' taken out is 'IRE'.
'showing' acts as a link.
(Other definitions for ire that I've seen before include "Losing head" , "Anger, annoyance" , "Paddy" , "Irritation, anger" , "Strong feeling" .)
