Where an intermediary goes (7)
I believe the answer is:
between
'where' is the definition.
Both the definition and answer are adverbs. Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for between that I've seen before include "In the space separating two objects" , "Been wet (anag.)" , "In the period separating (two events)" , "Betwixt" , "needle, not the smallest"" .)
