That woman is in the right (3)
I believe the answer is:
her
'that woman' is the definition.
('her' refers to a woman)
'in the right' is the wordplay.
'in' indicates a hidden word.
'HER' is hidden in the letters of 'the right'.
'is' is the link.
(Other definitions for her that I've seen before include "Belonging to the woman" , "Pronoun used of ship" , "The female's" , "Belonging to a female" , "She, objectively" .)
