Partner of hee or hem (3)
I believe the answer is:
haw
'partner of hee or hem' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for haw that I've seen before include "Fruit of the may tree" , "Hem and . . . - grope for words" , "Hedge fruit" , "Fruit of the hawthorn" , "Fruit of a thorny bush" .)
