renegue

I'm a little stuck... Click here to teach me more about this clue!

'go back' is the definition.
'renegue' can be an answer for 'back' (I've seen this before). I am unsure of the 'go' bit.

'green arrangement eu u-turn' is the wordplay.
'arrangement' is an anagram indicator.
'u-turn' says the letters should be written backwards.
'eu' back-to-front is 'ue'.
'green' is an anagram of 'reneg'.
'reneg'+'ue'='RENEGUE'

'on' is the link.

Can you help me to learn more?

(Other definitions for renegue that I've seen before include "Welsh" , "Fail to fulfil an obligation" , "Revoke at cards" , "Abandon" , "Deny" .)
