Navigation with Poles winding down (6)
I believe the answer is:
slalom
'down' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for slalom that I've seen before include "Type of ski race" , "Windy skiing event" , "Skiers' obstacle race" , "Ski race down zig-zag course" , "Winding ski-run" .)
