Mended in the manner persuaded (5)
I believe the answer is:
soled
'mended' is the definition.
(soling is a kind of mending)
'manner persuaded' is the wordplay.
'manner' becomes 'so' (I can't justify this - if you can you should give a lot more credence to this answer).
'persuaded' becomes 'led'.
'so'+'led'='SOLED'
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for soled that I've seen before include "Repaired shoe" , "Pulled at one time" .)
