Withdraw writing by virtuoso sending up good books (6)
I believe the answer is:
recant
'withdraw' is the definition.
(thesaurus)
'by virtuoso sending up good books' is the wordplay.
'by' means one lot of letters go next to another.
'virtuoso' becomes 'ace' ('ace' can be a synonym of 'virtuoso').
'sending up' says the letters should be written backwards.
'good' becomes 'r' (I am not sure about this - if you are sure you should believe this answer much more).
'books' becomes 'nt' (New Testament).
'ace' written backwards gives 'eca'.
'eca' after 'r' is 'reca'.
'reca'+'nt'='RECANT'
'writing' is the link.
Can you help me to learn more?
(Other definitions for recant that I've seen before include "Publicly withdraw" , "Take back in canter" , "Go back on a statement of belief" , "Disown" , "Renounce a former opinion or belief" .)
