It was a long-shot bet, getting her cut distributed (9)
I believe the answer is:
trebuchet
'it was a long-shot' is the definition.
The definition suggests a singular noun which matches the answer.
'bet getting her cut distributed' is the wordplay.
'getting' says to put letters next to each other.
'distributed' is an anagram indicator.
'bet'+'her'+'cut'='bethercut'
'bethercut' is an anagram of 'TREBUCHET'.
Can you help me to learn more?
(Other definitions for trebuchet that I've seen before include "onager?" , "Medieval siege engine" , "Medieval engine of war" , "Old slinger" , "Old weapon" .)
