Possibly hire one female character (7)
I believe the answer is:
heroine
'female character' is the definition.
'heroine' can be an answer for 'character' (heroine is a kind of character). I'm unsure of the 'female' bit.
'possibly hire one' is the wordplay.
'possibly' indicates anagramming the letters.
'hire'+'one'='hireone'
'hireone' anagrammed gives 'HEROINE'.
Can you help me to learn more?
(Other definitions for heroine that I've seen before include "Brave woman" , "Brave female" , "Eg, Emma, Jane Eyre" , "Leading lady" , "Emma, for example" .)
