Back twisted once more? (8)
I believe the answer is:
returned
'back twisted' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'once more?' is the wordplay.
I cannot really understand how this works, but
'once more?' could be 're' (prefix in words like 're-emerge' or 're-enter') and 're' is present in the answer.
The remaining letters 'turned' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for returned that I've seen before include "Honoured by the electorate" , "Went, came or gave back" , "Sent back" , "Came back - voted in" , "dishonoured by the bank" .)
