Legendary river, we hear, in wood (6)
I believe the answer is:
sticks
'wood' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sticks that I've seen before include "Glues" , "Stands" , "Is bogged down" , "Adheres" , "Old fogeys" .)
