Sporting way to risk a wet upset! (8)
I believe the answer is:
waterski
'sporting way' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'risk a wet upset' is the wordplay.
'upset' indicates anagramming the letters.
'risk'+'a'+'wet'='riskawet'
'riskawet' is an anagram of 'WATERSKI'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for waterski that I've seen before include "Engage in sport" , "Take part in a sport" .)
