Shelter for runners and climbers, perhaps? (6)
I believe the answer is:
wigwam
'shelter' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for wigwam that I've seen before include "Teepee" , "Tent once used by Native American" , "A Red Indian's tent" , "Tent formerly used by American Indians" , "Tent of skins and poles once used by native Americans" .)
