Revolutionary female cook (4)
I believe the answer is:
chef
'cook' is the definition.
(chef is a kind of cook)
'revolutionary female' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'female' becomes 'f' (abbreviation).
'che'+'f'='CHEF'
(Other definitions for chef that I've seen before include "Saucier" , "one in the restaurant" , "member of kitchen staff" , "who has a set of knives?" , "Cooker?" .)
