Feminine commercial's causing rages (4)
I believe the answer is:
fads
'rages' is the definition.
('fad' can be a synonym of 'rage')
'feminine commercial's' is the wordplay.
'feminine' becomes 'f' (abbreviation listed in Chambers).
'commercial's' becomes 'ads'.
'f'+'ads'='FADS'
'causing' acts as a link.
(Other definitions for fads that I've seen before include "Short-lived crazes" , "Fashions or vogues" .)
