SOS with Clare wrecking game (8)
I believe the answer is:
lacrosse
'game' is the definition.
(lacrosse is a sport)
'sos with clare wrecking' is the wordplay.
I cannot really see how this works, but
an anagram of 'sos' is 'oss' which is present in the answer.
an anagram of 'clare' is 'lacre' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lacrosse that I've seen before include "Game played with netted sticks" , "Game played with a netted stick" , "Game played with nets on sticks" , "Sport played with sticks" , "Ball game using netted stick" .)
