Female contributor to the Greyfriars Herald (3)
I believe the answer is:
she
'female' is the definition.
('she' refers to a woman)
'contributor to the greyfriars herald' is the wordplay.
'contributor to' indicates a hidden word (the letters of the answer contribute to the clue).
'SHE' is hidden within 'greyfriars herald'.
(Other definitions for she that I've seen before include "That woman" , "H. Rider Haggard novel" , "Rider's novel" , "1887 Rider Haggard novel" , "- - Loves You (Beatles)" .)
