Female in entourage is handmaid (6)
I believe the answer is:
geisha
'female' is the definition.
(geisha is a kind of female)
'in entourage is handmaid' is the wordplay.
'in' indicates the answer is hidden within the clue.
'GEISHA' is hidden in the letters of 'entourage is handmaid'.
(Other definitions for geisha that I've seen before include "One employed to look after men" , "A Japanese woman who entertains men" , "Entertaining girl" , "Japanese serving girl" , "Professional Japanese hostess and entertainer of men" .)
