Here, there's a Green (6)
I believe the answer is:
hither
'here' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hither that I've seen before include "Hit her, being towards this place" , "Here (arch)" , "In this direction" , "so far" , "Towards this place - not yonder" .)
