Maritime pronoun (3)
I believe the answer is:
she
'maritime pronoun' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for she that I've seen before include "1887 Rider Haggard novel" , "way to refer to mare" , "fiction" , "H. Rider Haggard novel" , "Female pronoun" .)
