I loan out the work of G&S (8)
I believe the answer is:
iolanthe
'work of gs' is the definition.
(Iolanthe is an opera by Gilbert and Sullivan)
'i loan out the' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'loan' anagrammed gives 'olan'.
'i'+'olan'+'the'='IOLANTHE'
(Other definitions for iolanthe that I've seen before include "G&S operetta" , "G&S's eponymous fairy" , "Gilbert and Sullivan opera" , "The Peer and the Peri is its alternative title" , "Staged work" .)
