Waiter’s blow up Everest helper? (5)
I believe the answer is:
piton
This might be a double definition.
'waiter's' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'blow up everest helper?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
Can you help me to learn more?
(Other definitions for piton that I've seen before include "Climber's iron peg" , "What mountaineer requires" , "Mountaineering tool" , "Mountaineer's metal spike" , "climber needs this" .)
