Rope binding one officer that’s convicted (6)
I believe the answer is:
guilty
'convicted' is the definition.
(similar in meaning)
'rope binding one officer' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'officer' could be 'lt' (I've seen this in other clues) and 'lt' is found within the answer.
'rope' could be 'guy' (I have seen 'Steadying rope ' mean 'guy' so perhaps 'rope' could also mean 'guy') and 'guy' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for guilty that I've seen before include "Blameworthy, at fault" , "Responsible for misdeed" , "Having done wrong - a plea in court" , "Jury verdict - the accused did it" , "(Found) responsible for offence" .)
