One used to hang back in game so one-sided (5)
I believe the answer is:
noose
'one used to hang' is the definition.
I know that 'hang' relates to this answer.
'back in game so one-sided' is the wordplay.
'back' shows that the letters should be reversed in order.
'in' indicates the answer is hidden within the clue.
'esoon' can be found hidden inside 'game so one sided'.
'esoon' written backwards gives 'NOOSE'.
Can you help me to learn more?
(Other definitions for noose that I've seen before include "trap" , "Hangman's halter" , "form of punishment" , "Ring of rope" , "Snare, restraint" .)
