She's a climber (3)
I believe the answer is:
ivy
I believe this clue is a double definition.
'she's' is the first definition.
(woman's name)
'a climber' is the second definition.
(ivy is a climbing plant)
(Other definitions for ivy that I've seen before include "Trailer" , "Evergreen creeping plant" , "Creeper plant" , "Girl's name; climber" , "woman" .)
