Having called, we’re told, had managed to extract from (5)
I believe the answer is:
wrung
'we're told had managed to extract from' is the definition.
I can't judge whether this defines the answer.
'having called' is the wordplay.
'having' becomes 'w' (I can't justify this - if you can you should give a lot more credence to this answer).
'called' becomes 'rung' (ring can mean to call on the phone).
'w'+'rung'='WRUNG'
Can you help me to learn more?
(Other definitions for wrung that I've seen before include "Squeezed and twisted" , "Twisted and compressed" , "Coerced" .)
