Send back coat over silent treatment to manage alone (3,6)
I believe the answer is:
run itself
'manage alone' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'send back coat over silent treatment' is the wordplay.
'send back' is a reversal indicator.
'coat' becomes 'fur' (fur is a kind of coat).
'over' means one lot of letters goes inside another.
'treatment' is an anagram indicator (letters treated or processed differently).
'fur' in reverse letter order is 'ruf'.
'silent' anagrammed gives 'nitsel'.
'ruf' enclosing 'nitsel' is 'RUN ITSELF'.
'to' acts as a link.
Can you help me to learn more?
(Another definition for run itself that I've seen is " Need no guidance to cope".)
