Where skiers possibly step out of line? (5)
I believe the answer is:
piste
This might be a double definition.
'where skiers possibly step' is the first definition.
The definition suggests a singular noun which matches the answer.
'line?' is the second definition.
(thesaurus)
'out of' acts as a link.
Can you help me to learn more?
(Other definitions for piste that I've seen before include "A ski run of compacted snow" , "Ski trail" , "Skiing run" , "Skiing course" , "Ski slope" .)
